This is a barrier to maize diversification and improvement in regions where a large share of the world's corn production takes place. For investigating early flowering time adaptation, a tightly controlled parallel selection experiment spanning a 28° latitudinal range (∼3,100 km) across the United States was conducted. First, a tropical synthetic population (TropicS‐G0) (Reg. no. GP‐605, PI 698625) of maize was created from seven inbred parents. The molecular genetic diversity in TropicS‐G0 is representative of tropical inbreds that are differentiated from the prevailing germplasm used for hybrid production in the United States. Admixture analysis and genome simulation showed that breeding of TropicS‐G0 captured the parental genomes mostly at random, as intended prior to selection. With TropicS‐G0 as a common base population, a standardized protocol was used to recurrently select for early flowering time at eight locations for two generations, giving rise to location‐specific lineages (TropicS‐G1‐PR, Reg. no.

Breeding and selection occurred under biodynamic conditions in Wisconsin, on an organic winter nursery in Puerto Rico, a biodynamic winter nursery in Hawaii, and a conventional winter nursery in Chile. Emphasis is on improving protein quality, carotenoid content, competitiveness with weeds, nitrogen (N) efficiency/N 2 fixation, and cross incompatibility to pollen from genetically engineered (GE) maize. Philosophy is that the plant species is a responding partner in the breeding process. Adaptation and selection emphasizes vigor and yield under N limited conditions. The Ga1 and Tcb1 alleles were utilized to induce cross incompatibility. The program resulted in inbreds and hybrids with increased N efficiency and protein quality coupled with softer grain texture, more chlorophyll in foliage, and densely branched root growth in the topsoil relative to conventionally bred cultivars under N limited conditions. Grain protein quality was improved by utilizing opaque kernels that emerged in populations during the course of the program in surprisingly high frequencies. N efficiency was accentuated by breeding with landraces that may fix N 2 with microbes coupled with selection for response traits under N-limited conditions. When grown next to conventional hybrids, the best hybrids from this program have exhibited 30% more methionine and 16% more protein in grain and more protein/ha.}, number={1}, journal={OPEN AGRICULTURE}, author={Goldstein, W. and Jaradat, A.

Current gametophytic systems rely entirely on the strong allele of Gametophyte Factor 1 ( Ga1‐s ) to impart the selective barrier needed in these hybrids. This allele, however, is naturally overcome by another allele at the same locus ( Ga1‐m ), which is only detectable by specific evaluation, allowing it to go undetected in breeding lines, thus creating a scenario with substantial risk to Ga1‐s hybrids. Other gametophytic systems exist but have parallel allelic structure with possibly parallel risks, especially from m‐ type alleles. By screening a set of maize genetic resources, we assessed the risk posed by the Ga1‐m allele. We identified the allele in several populations readily useful for expanding the genetic base of commercial maize, including several Germplasm Enhancement of Maize lines. To examine the possible distribution of m‐ type alleles at other key gametophytic loci, we screened the maize nested association mapping population founder lines for the presence of m‐ type gametophytic alleles, identifying 19 previously unreported m‐ type gametophytic alleles in these lines. Our results also highlight the frequent concomitancy of gametophytic alleles at different loci, the full interactions of which are ignored by standard phenotyping methods that consider individual loci, confounding allele status determination. We provide a method for determining allele status at multiple gametophytic loci and highlight the implications of concomitant alleles, especially Ga1‐m and Tcb1‐m , on the possible deployment of new barrier systems.}, number={2}, journal={CROP SCIENCE}, author={Jones, Zachary G. and Goodman, Major M.}, year={2018}, pages={719–727} }

Teosinte ( Z. mays ssp. parviglumis), the wild progenitor of maize, offers a novel source of resistance alleles that may have been lost during domestication. The aims of this study were to identify teosinte alleles that, when present in a temperate maize background, confer a significant level of resistance to SLB. Ten populations of BC 4 S 2 near isogenic lines (NILs), developed by crossing 10 different teosinte accessions to the maize inbred B73, comprising 774 lines in total, were screened for SLB resistance. Quantitative trait locus (QTL) analysis identified four significant QTL associated with SLB in bins 2.04, 3.04, 3.05, and 8.05. Sixteen individual NILs which were significantly different to the susceptible recurrent parent, B73 and which were carrying at least one of the teosinte‐derived resistance alleles were used to develop F 2:3 populations by crossing each to B73 followed by two rounds of self‐pollination. These F 2:3 populations were evaluated for SLB resistance and genotyped at the loci of interest. In 13 of 19 cases single marker analysis validated allelic substitution effects predicted from the original NIL population analysis, while in five cases we were not able to validate the effects and in one case a significant effect was detected in the opposite to the predicted direction.

The Ga1‐m allele overcomes the pollen barrier imparted by Ga1‐s , opening any system using it to potential contamination. The Ga1‐m allele, although previously thought rare, has been shown to be abundant in Mexican commercial maize ( Z. mays L.), and has been identified in a US ex‐Plant Variety Protection (PVP) line. The requirement for specific evaluation to detect the allele, coupled with efforts to increase the genetic base of maize, create a considerable risk of the unintentional release of Ga1‐m ‐carrying materials. Resistance to Ga1‐m has been previously identified, providing a possible way to eliminate the risk posed by Ga1‐m but comes in an unadapted sweetcorn background. Through field evaluation, we tested commercial and publically available popcorn for resistance to Ga1‐m , all of which were uniformly susceptible. There is, therefore, a need to identify and integrate Ga1‐m resistance into commercial popcorn inbred lines and hybrids. Although the use of existing Ga1‐m resistant sources is an option, background differences will likely be problematic for producing useable inbred lines. We suggest the use of molecular tools to aid in specific backcrossing of the Ga1‐m resistance allele or identification of Ga1‐m resistance in a popcorn background, for which we suggest an evolutionary‐based approach.}, number={5}, journal={CROP SCIENCE}, author={Jones, Zachary G. and Goodman, Major M.}, year={2016}, pages={2594–2599} }

Genetic studies have provided firm evidence that maize was domesticated from Balsas teosinte ( Zea mays subspecies parviglumis ), a wild relative that is endemic to the mid- to lowland regions of southwestern Mexico. An interesting paradox remains, however: Maize cultivars that are most closely related to Balsas teosinte are found mainly in the Mexican highlands where subspecies parviglumis does not grow. Genetic data thus point to primary diffusion of domesticated maize from the highlands rather than from the region of initial domestication. Recent archeological evidence for early lowland cultivation has been consistent with the genetics of domestication, leaving the issue of the ancestral position of highland maize unresolved. We used a new SNP dataset scored in a large number of accessions of both teosinte and maize to take a second look at the geography of the earliest cultivated maize. We found that gene flow between maize and its wild relatives meaningfully impacts our inference of geographic origins. By analyzing differentiation from inferred ancestral gene frequencies, we obtained results that are fully consistent with current ecological, archeological, and genetic data concerning the geography of early maize cultivation.}, number={3}, journal={PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA}, author={Heerwaarden, Joost and Doebley, John and Briggs, William H. and Glaubitz, Jeffrey C. and Goodman, Major M. and Sanchez Gonzalez, Jose de Jesus and Ross-Ibarra, Jeffrey}, year={2011}, month={Jan}, pages={1088–1092} }

Using Bayesian clustering, we detected four main clusters consisting of highland Mexican, northern United States (US), tropical lowland, and Andean races. Phylogenetic analysis indicated that the southwestern US was an intermediary stepping stone between Mexico and the northern US. Furthermore, southeastern US races appear to be of mixed northern flint and tropical lowland ancestry, while lowland middle South American races are of mixed Andean and tropical lowland ancestry. Several cases of post‐Columbian movement of races were detected, most notably from the US to South America. Of the four main clusters, the highest genetic diversity occurs in highland Mexican races, while diversity is lowest in the Andes and northern US.

Entry mean and average genetic correlations between disease ratings in different environments were high (0.78 to 0.89 and 0.9, respectively) and the overall entry mean heritability for SLB resistance was 0.89. When weighted mean disease ratings were fitted to a model using multiple interval mapping, seven potential quantitative trait loci (QTL) were identified, the two strongest being on chromosomes 3 (bin 3.04) and 9 (bin 9.03–9.04). These QTL explained a combined 80% of the phenotypic variation for SLB resistance. Some time-point-specific SLB resistance QTL were also identified.

Dense seed is preferred by dry millers and for alkaline processing, and can command a price premium at market. This study attempted to increase kernel density in a backcrossing program for two inbreds of maize using two selection techniques, specific gravity of kernels and the percentage of sinking kernels in a salt solution (or sinkers). Two inbreds, B73G and A632, were crossed with synthetics exhibiting apparent high kernel density, and several generations of backcrossing and self‐pollination followed. Examples of mean comparisons of backcross‐derived inbreds with the recurrent parents, B73G and A632 are as follows: B73G–Specific gravity, 1.251 and 1.206; Sinkers, 62.3 and 14.9%; and A632–Specific gravity, 1.266 and 1.250; Sinkers 45.4 and 29.1%.

Maize, a classical model for genetic studies, is an important crop species and also the most diverse crop species known. On average, two randomly chosen maize lines have one single-nucleotide polymorphism every ∼100 bp; this divergence is roughly equivalent to the differences between humans and chimpanzees. This exceptional genotypic diversity underlies the phenotypic diversity maize needs to be cultivated in a wide range of environments. The Molecular and Functional Diversity in the Maize Genome project aims to understand how selection has shaped molecular diversity in maize and then relate molecular diversity to functional phenotypic variation. The project will screen 4000 loci for the signature of selection and create a wide range of maize and maize–teosinte mapping populations. These populations will be genotyped and phenotyped, permitting high-power and high-resolution dissection of the traits and relating the molecular diversity to functional variation.

Although this necessary phenotypic variability exists in diverse maize, most research is conducted using a small subset of inbred lines. An association population of 302 lines is now available – a valuable research tool that captures a large proportion of the alleles in cultivated maize. Provided that appropriate statistical models correcting for population structure are included, this tool can be used in association analyses to provide high-resolution evaluation of multiple alleles. This study describes the population structure of the 302 lines, and investigates the relationship between population structure and various measures of phenotypic and breeding value. On average, our estimates of population structure account for 9.3% of phenotypic variation, roughly equivalent to a major quantitative trait locus (QTL), with a high of 35%. Inclusion of population structure in association models is critical to meaningful analyses. This new association population has the potential to identify QTL with small effects, which will aid in dissecting complex traits and in planning future projects to exploit the rich diversity present in maize.}, number={6}, journal={PLANT JOURNAL}, author={Flint-Garcia, SA and Thuillet, AC and Yu, JM and Pressoir, G and Romero, SM and Mitchell, SE and Doebley, J and Kresovich, S and Goodman, MM and Buckler, ES}, year={2005}, month={Dec}, pages={1054–1064} }

Starch concentration and composition in the maize (Zea mays ssp mays) kernel are complex traits controlled by many genes.

Major kernel composition traits, such as protein, oil, and starch concentration, were assessed as well as important starch composition quality traits, including pasting properties and amylose levels. Overall, bt2, sh1, and sh2 showed significant associations for kernel composition traits, whereas ae1 and sh2 showed significant associations for starch pasting properties. ae1 and sh1 both associated with amylose levels. Additionally, haplotype analysis of sh2 suggested this gene is involved in starch viscosity properties and amylose content.

One objective of this study was to determine if exotic‐derived alleles contributing to enhanced testcross agronomic performance were maintained in semiexotic lines created by inbreeding and pedigree selection. A second objective was to determine if first‐generation semiexotic lines could produce hybrids with agronomic performance comparable to commercial U.S. hybrids. One hundred sixty‐four semiexotic inbred lines were developed from crosses between temperate‐adapted inbred line Mo44 and 23 Latin American maize accessions. Mo44 and each semiexotic line were testcrossed to temperate hybrid LH132 × LH51 for evaluations. In first‐stage replicated yield trials, testcrosses of 18 semiexotic lines, representing six different races, had significantly greater grain yields than the Mo44 testcross. Advanced yield evaluations were performed on check entries and 33 selected semiexotic line testcrosses in three additional environments. Across 10 environments, 12 semiexotic line testcrosses exhibited significantly greater grain yield than the Mo44 testcross, indicating recovery of favorable exotic alleles. Semiexotic testcrosses were not competitive with commercial hybrids for grain yield but were similar to or better than commercial hybrids for grain moisture and lodging resistance. Many superior accessions represent relatively recent introductions into regions from which they were collected.

To explain this high level of diversity in maize, several authors have proposed that maize landraces were the products of multiple independent domestications from their wild relative (teosinte). We present phylogenetic analyses based on 264 individual plants, each genotyped at 99 microsatellites, that challenge the multiple-origins hypothesis. Instead, our results indicate that all maize arose from a single domestication in southern Mexico about 9,000 years ago. Our analyses also indicate that the oldest surviving maize types are those of the Mexican highlands with maize spreading from this region over the Americas along two major paths. Our phylogenetic work is consistent with a model based on the archaeological record suggesting that maize diversified in the highlands of Mexico before spreading to the lowlands.

One problem faced by maize breeders attempting to breed for resistance to gray leaf spot is the high degree of genotype-environment interactions observed in disease trials. In North Carolina gray leaf spot trials conducted at four locations in the western part of the state, we found consistent hybrid-location interactions over the 1995 and 1996 growing seasons. Isolates of C. zeae-maydis from those test locations were evaluated on the same hybrids used in the multilocation testing at a location in central North Carolina that does not have a history of gray leaf spot. The hybrid-isolate interactions observed in the isolate trial mirrored the hybrid-location effects seen in the multilocation testing. Most of the interactions arose from changes in the magnitude of differences between hybrids when inoculated with the isolates rather than from any change in hybrid ranking. Analysis of internal transcribed spacer-restriction fragment length polymorphisms (RFLPs) and mitochondrial rDNA RFLPs of those isolates and others revealed that both type I and type II sibling species of C. zeae-maydis, as well as C. sorghi var. maydis, are isolated from typical gray leaf spot lesions. Breeders should use the most aggressive isolates of C. zeae-maydis to maximize discrimination between genotypes in gray leaf spot trials.}, number={10}, journal={PLANT DISEASE}, author={Carson, ML and Goodman, MM and Williamson, SM}, year={2002}, month={Oct}, pages={1089–1093} }

We report patterns of local and genome-wide LD in 102 maize inbred lines representing much of the worldwide genetic diversity used in maize breeding, and address its implications for association studies in maize. In a survey of six genes, we found that intragenic LD generally declined rapidly with distance ( r 2 < 0.1 within 1500 bp), but rates of decline were highly variable among genes. This rapid decline probably reflects large effective population sizes in maize during its evolution and high levels of recombination within genes. A set of 47 simple sequence repeat (SSR) loci showed stronger evidence of genome-wide LD than did single-nucleotide polymorphisms (SNPs) in candidate genes. LD was greatly reduced but not eliminated by grouping lines into three empirically determined subpopulations. SSR data also supplied evidence that divergent artificial selection on flowering time may have played a role in generating population structure. Provided the effects of population structure are effectively controlled, this research suggests that association studies show great promise for identifying the genetic basis of important traits in maize with very high resolution.}, number={20}, journal={PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA}, author={Remington, DL and Thornsberry, JM and Matsuoka, Y and Wilson, LM and Whitt, SR and Doeblay, J and Kresovich, S and Goodman, MM and Buckler, ES}, year={2001}, month={Sep}, pages={11479–11484} }

Restriction fragment length polymorphisms (RFLPs) and isozymes can serve as genetic markers for estimating divergence or diversity; however, the limited number of polymorphic isozyme loci available and the labor intensive and time consuming nature of RFLPs make their use for this purpose prohibitive. Simple sequence repeats (SSRs), when resolved using agarose gels, may be a viable and costeffective alternative to RFLPs and isozymes. Ninety-four elite maize inbred lines, representative of the genetic diversity among lines derived from the Corn Belt Dent and Southern Dent maize races, were assayed for polymorphism at 70 SSR marker loci using agarose gels. The 365 alleles identified served as raw data for estimating genetic similarities among these lines. The patterns of genetic divergence revealed by the SSR polymorphisms were consistent with known pedigrees. A cluster analysis placed the inbred lines in nine clusters that correspond to major heterotic groups or market classes for North American maize. A unique fingerprint for each inbred line could be obtained from as few as five SSR loci. The utility of polymerase chain reaction (PCR)-based markers such as SSRs for measuring genetic diversity, for assigning lines to heterotic groups and for genetic fingerprinting equals or exceeds that of RFLP markers, a property that may prove a valuable asset for a maize breeding program.}, number={4}, journal={CROP SCIENCE}, author={Senior, ML and Murphy, JP and Goodman, MM and Stuber, CW}, year={1998}, pages={1088–1098} }

The objective of this study was to determine if selection for reduced grain moisture content at harvest in a tropical maize population indirectly influenced grain yield potential. Two hundred sixteen temperately‐adapted S 4 lines were derived in 1991 at Raleigh, NC, from Cycle 9 of recurrent phenotypic selection for reduced grain moisture at harvest in the tropical maize population TROPHY, and these were testcrossed in 1992 at Raleigh, NC, to the temperate hybrid B73 Ht × Mo17 Ht . Selected subsets of these testcrosses were evaluated for their agronomic potential in seven environments over two years, and their performance was compared with that of Cycle 0 S 0 testcrosses as well as three public and three commercial F 1 hybrids. Selected Cycle 9 S 4 testcrosses had higher mean grain yield (7.14 Mg ha ‒1 ) and lower mean grain moisture at harvest (184 g kg −1 ) than the Cycle 0 So testcrosses (6.77 Mg ha −1 , and 189 g kg −1 respectively). The highest yielding Cycle 9 S 4 testcrosses were comparable to the commercial hybrid LH132 × LH51. This study supported the conclusion that ergonomically competitive inbred lines with acceptable grain moisture content at harvest can be derived from 100% tropical germplasm.}, number={5}, journal={CROP SCIENCE}, author={Hawbaker, MS and Hill, WS and Goodman, MM}, year={1997}, pages={1650–1655} }

For base collections to function, they must provide for regeneration, characterization, documentation, and evaluation of their materials. The quality of a germ plasm system should be judged on the basis of the quality of the materials available to scientists.
