Merr.). The study aimed to identify yield-related quantitative trait loci (QTLs) in soybeans using a population of 160 F4-derived lines from ‘Hutcheson’ × PI 471938 crosses, which were cultivated under rain-fed and irrigated conditions. Seed yield was determined based on a total of nine irrigated and five rain-fed environments over two years. Twenty and twenty-seven SSR markers associated with yield (p ≤ 0.05) were identified in the irrigated and rain-fed environments, respectively. Four markers accounted for 22% of the yield variation in the irrigated environments (IR-YLD) and five markers explained 34% of the yield variation in the rain-fed environments (RF-YLD). Two independent IR-YLD and RF-YLD QTLs on chromosome (Chr) 13 (LG-F) were mapped to the Satt395-Sat_074 interval (4.2 cM) and near Sat_375 (3.0 cM), which explained 8% (LOD = 2.6) and 17% (LOD = 5.5) of the yield variation, respectively. The lines homozygous for the Hutcheson allele at the IR-YLD QTL linked to Sat_074 averaged 100 kg ha−1 higher yield than the lines homozygous for the PI 471938 allele. At two independent RF-YLD QTLs on Chr 13 and Chr 17, the lines homozygous for the PI 471938 alleles were 74 to 101 kg ha−1 higher in yield than the lines homozygous for the Hutcheson alleles. Three of the five significant SSR markers associated with RF-YLD were located in a genomic region known for canopy-wilting QTLs, in which the favorable alleles were inherited from PI 471938. The identification of yield-QTLs under the respective rain-fed and irrigated environments provides knowledge regarding differential responses of yield under different irrigation conditions, which will be helpful in developing high-yielding soybean cultivars.}, number={11}, journal={AGRONOMY-BASEL}, author={Lee, Geung-Joo and Lee, Sungwoo and Carter Jr, Tommy E. and Shannon, Grover and Boerma, H.

Merr.). In this study, the ability of soybean genotypes to recover transpiration and leaf gas exchange capacity following re-watering from soil drying was investigated. The plants were subjected to controlled water-deficit stress and recovery in growth-chamber experiments. Transpiration was measured on five soybean genotypes and photosynthesis rates on two select genotypes. After water re-supply, transpiration was initially low but increased until a stable rate was reached on day 3, to about 50% to 100% of the rates of reference plants that had not been stressed. The largest difference in maximum transpiration recovery was between the varieties USDA-N8002 and Benning compared to the landrace Geden Shirazu, with Geden Shirazu having the lowest recovery. Photosynthesis and vapor-pressure-deficit response measurements did not show that restricted plant stomatal conductance was responsible for the limitation observed in Geden Shirazu recovery. Since all genotypes showed rapid recovery from water-deficit stress in 3 d, more rapid recovery was not indicated as a major candidate for improving soybean drought tolerance. However, the extent of recovery varied among genotypes and those genotypes that fully recovered to rates of well-watered plants such as Benning and USDA-N8002 would seemingly be advantageous for drought conditions.}, number={6}, journal={Journal of Crop Improvement}, publisher={Informa UK Limited}, author={Rosas-Anderson, Pablo and Sinclair, Thomas R. and Locke, Anna and Carter, Thomas E. and Rufty, Thomas W.}, year={2020}, month={May}, pages={785–799} } @article{mcneece_bagherzadi_carter_mian_2020, title={Registration of USDA-N7004 soybean germplasm with good yield, elevated seed protein, and 25% exotic pedigree from Tamahikari}, volume={14}, ISSN={["1940-3496"]}, DOI={10.1002/plr2.20039}, abstractNote={Abstract}, number={3}, journal={JOURNAL OF PLANT REGISTRATIONS}, author={McNeece, Brant T. and Bagherzadi, Laleh and Carter, Thomas E., Jr. and Mian, M.

These materials were released by the USDA‐ARS and the North Carolina Agricultural Research Service (March 2017) to expand the North American soybean breeding pool. The full‐sib breeding lines are 50% wild soybean by pedigree and developed through bulk breeding and pedigree selection. Marker analysis of 2455 well‐distributed polymorphic single‐nucleotide polymorphism loci revealed that individual breeding lines ranged from 21 to 40% alleles derived from wild soybean. Collectively, most of the wild soybean genome was transferred to the core set in that 5, 10, and 17 breeding lines captured 83, 98, and 99% of G. soja–derived polymorphic alleles. Physical linkage maps suggested that extensive recombination occurred between the G. max and G. soja genomes. The 17 breeding lines are well adapted to the southeastern United States, exhibited seed yield ranging from 75 to 97% of the domesticated parent, and are group VI or VII maturity. Some breeding lines displayed increased seed protein, oil, or methionine content, and all exhibited increased seed size as compared to the domesticated parent.

Plants were exposed to ozone treatment for 5 days in greenhouse chambers followed by visual scoring for foliar injury. Mean injury score in the mid-canopy was 16 % for Fiskeby III, and 81 % for Mandarin (Ottawa). Injury scores were lower in younger leaves for both parents and progeny, compared to scores in the older leaves. Segregation was consistent with multigenic inheritance.

Here we seek to understand how abiotic and biotic stresses associated with climate change can affect plant-herbivore interactions in a model crop species (soybean, Glycine max (L.) Merr.) by answering three questions: (1) Do the combined effects of abiotic and biotic stresses associated with climate change cause synergistic negative effects on plant biomass? (2) Can abiotic stress affect resistance of plants to insect herbivores? (3) Does genetic variation in plant traits modify a plant’s response to stress? We performed three experiments in controlled growth environments using up to 51 soybean genotypes selected to vary in numerous traits associated with drought and resistance against pests (e.g., insect herbivores, nematodes, and pathogenic fungi), and up to 3 generalist-feeding herbivorous noctuid moth species (Helicoverpa zea, Heliothis virescens, and Spodoptera exigua) that commonly feed on soybean in North America. Drought and herbivory had the largest and the most consistent negative effects on plant performance, reducing the above- and below-ground biomass by 10-45 %, whereas increased temperature had little to no effect on plants. Drought also increased susceptibility to generalist noctuid herbivores, but these results varied dramatically in magnitude and direction among plant genotypes. Our experiments show that the effects of abiotic and biotic stress on soybean biomass were largely due to the additive effects of these stresses, and there exists substantial genetic variation in the soybean germplasm pool we studied that could be used as a source of parental stock in breeding new crops that can more effectively tolerate and resist the combined negative effects of insect herbivory and drought.}, number={2}, journal={ARTHROPOD-PLANT INTERACTIONS}, author={Grinnan, Rose and Carter, Thomas E., Jr. and Johnson, Marc T.

Under moisture-deficit conditions, PI 416937 wilted more slowly in the field than elite cultivars and has been used as a parent in breeding programs to improve soybean productivity. A recombinant inbred line (RIL) population was derived from a cross between PI 416937 and Benning, and the population was phenotyped for canopy wilting under rain-fed field conditions in five distinct environments to identify the QTL associated with the canopy-wilting trait.

Five QTL inherited their positive alleles from PI 416937. Surprisingly, the other two QTL inherited their positive alleles from Benning. These putative QTL were co-localized with other QTL previously identified as related to plant abiotic stresses in soybean, suggesting that canopy-wilting QTL may be associated with additional morpho-physiological traits in soybean.

In 2007 and 2008, we tested two screening tactics to nondestructively estimate canopy coverage during the critical period for weed competition. Overhead photography at 3 and 5 weeks after emergence and light interception measurements at 4 and 6 weeks after emergence were compared in their ability to predict soybean and weed biomass at the end of the critical period for weed competition. Photographic digital image processing techniques were compared. Overhead photography at 5 weeks after emergence was most effective at predicting weed-free soybean biomass but overhead photography at 3 weeks after emergence was best able to predict weed biomass associated with soybean genotypes at the end of the critical period for weed competition.}, number={21}, journal={COMMUNICATIONS IN SOIL SCIENCE AND PLANT ANALYSIS}, publisher={Informa UK Limited}, author={Place, G.

Merr.] (Reg. No. GP‐366, PI 658498) was cooperatively developed and released by the USDA–ARS and the North Carolina Agricultural Research Service in October 2009 as a mid–Maturity Group VI germplasm with high‐protein seed, favorable yield potential, large seed size, and diverse pedigree. The unusual combination of high protein and favorable yield in this germplasm, plus its diverse genetic background, makes it a potentially desirable breeding stock for both specialty and commodity breeding programs. N6202 was developed through conventional breeding and is adapted to the southern United States. Average seed protein level was 457 g kg−1 (zero moisture basis), which was 33 g kg−1 greater (p < 0.05) than that of the control cultivar NC‐Roy. Average yield of N6202 was more than 90% of NC‐Roy over 65 environments. The 100‐seed weight of N6202 (21.4 g) was significantly greater (p < 0.05) than that of the largest‐seeded control cultivar Dillon (15.2 g).Twenty‐five percent of N6202's pedigree is derived from Japanese cultivar Fukuyataka. Fukuyataka is not known to be related to the genetic base of U.S. soybean. An additional 25% of N6202's pedigree traces to the Japanese cultivar Nakasennari, which appears in the pedigree of only one cultivar (its parent ‘N6201’). Thus, the release of N6202 broadens the genetic range of materials adapted for soybean breeding in the United States. N6202 exhibits a moderate level of the bleeding hilum trait in some environments.}, number={1}, journal={JOURNAL OF PLANT REGISTRATIONS}, author={Carter, T. E., Jr. and Rzewnicki, P.

A first step in the breeding of resistant cultivars for a crop such as soybean (Glycine max (L.) Merr.) is identification of sources of O3 resistance genes. Thirty ancestral lines of soybean were screened for differences in O3 foliar injury under greenhouse conditions. The ancestors represented 92% of the genetic base of North American soybean as determined by pedigree analysis. Injury among ancestors ranged from 5 to 50% of leaf area, based on response of the five oldest main stem leaves, indicating both the presence of substantial genetic variation for O3 injury among the ancestors as well as resistance levels greater than that of the standard control cultivar, resistant Essex (15% injury). Ancestral types Fiskeby 840-7-3 and Fiskeby III exhibited the greatest foliar resistance and PI 88788 the least. A subsequent field study confirmed the foliar resistance of the Fiskeby types. Resistant ancestors identified here are proposed for inheritance and DNA mapping studies to determine the genetic basis of foliar resistance. Because the presence of O3-resistant ancestors suggested that resistant descendents may exist in addition to the resistant control Essex, a method was developed to facilitate their identification. A predicted O3-resistance score was calculated for 247 publicly-released cultivars, based on pedigree analysis and ancestral response to ozone. Using this approach, the 32 public cultivars most closely related to resistant ancestors and, thus, most likely to be resistant were identified as priority candidates for future screening efforts. Predicted scores from the analysis suggested that cultivars from the Midwest may be more sensitive to foliar injury, on average, than Southern cultivars.}, number={3}, journal={FIELD CROPS RESEARCH}, author={Burkey, Kent O. and Carter, Thomas E., Jr.}, year={2009}, month={Apr}, pages={207–217} } @article{charlson_bhatnagar_king_ray_sneller_carter_purcell_2009, title={Polygenic inheritance of canopy wilting in soybean [Glycine max (L.)

Soybean cultivars differ in how quickly they wilt during water-deficit stress, and this trait may lead to yield improvement during drought. The objective of this study was to determine the genetic mechanism of canopy wilting in soybean using a mapping population of recombinant inbred lines (RILs) derived from a cross between KS4895 and Jackson. Canopy wilting was rated in three environments using a rating scale of 0 (no wilting) to 100 (severe wilting and plant death). Transgressive segregation was observed for the RIL population with the parents expressing intermediate wilting scores. Using multiple-loci analysis, four quantitative trait loci (QTLs) on molecular linkage groups (MLGs) A2, B2, D2, and F were detected (P 140 and 175 g kg−1 palmitic and total saturated fatty acid contents, respectively. No family produced greater oleic acid content than N87‐2122‐4. Some families produced >640 g kg−1 linoleic acid and total polyunsaturates exceeding 720 g kg−1, while selected individuals produced >750 g kg−1 total polyunsaturates in both the F2:3 parental and F2:4 progeny generations. High narrow‐sense heritability estimates for palmitic (h2 = 0.67 to 0.98) and linoleic (h2 = 0.44 to 0.80) acid contents suggested that individual F2 plants can be selected for either trait. However, the smaller heritabilities for oleic (h2 = 0.36 to 0.66) and linolenic (h2 = 0.10 to 0.47) acid contents necessitate selection based on family means. Analyzing these selected wild soybean crosses has demonstrated G. soja may be a useful source of genes to extend genotypic variation for linoleic and total polyunsaturated fatty acid contents. Genes for greater saturate content in PI 424031 may extend variation currently available in mutant soybean germplasm. However, it appears unlikely that G. soja would be useful for increasing oleic acid content above levels in existing soybean mutants.}, number={5}, journal={CROP SCIENCE}, author={Rebetzke, GJ and Pantalone, VR and Burton, JW and Carter, TE and Wilson, RF}, year={1997}, pages={1636–1640} } @article{manjarrezsandoval_carter_webb_burton_1997, title={Heterosis in soybean and its prediction by genetic similarity measures}, volume={37}, ISSN={["1435-0653"]}, DOI={10.2135/cropsci1997.0011183X003700050005x}, abstractNote={Coefficient of parentage (CP) and restriction fragment length polymorphism‐based genetic similarity estimates (RFLP‐GS) have been proposed as measures of genetic distance in crop species. If these measures are to have application in practical breeding, it is important to validate their utility in predicting genetic traits of interest such as heterosis. The objectives of this paper were to (i) estimate heterosis for yield in soybean [Glycine max (L.) Merr.] adapted to the southern USA, and (ii) predict heterosis by means of CP and RFLP‐GS as genetic distance measures. Twenty‐four F2 populations were developed by crossing three testers (‘Young’, ‘Centennial’, and ‘Tracy’) eight contrasting parents, representing a wide range of CP and RFLPGS. The experimental material was divided into three sets representing the testers above, and was evaluated in eight replications at Clayton and Plymouth, NC, in 1994. Midparent heterosis for yield was 7.9, 4.5, and 7.9% for Sets 1, 2, and 3, respectively. Heterosis was 3.5, 1.6, and 3.0% for 100‐seed weight, and 4.1, 5.4, and 13.2% for plant height. The CP and RFLP‐GS were highly correlated (r = 0.80, 0.92 and 0.95 for Sets 1, 2, and 3, respectively, P = 0.01), but neither predicted heterosis well for yield averaged across locations because of a large genotype × environment (G × E) interaction. In contrast, CP and RFLP‐GS predicted heterosis well for 100‐seed weight and plant height in two of the three sets averaged over locations. Our estimates of high parent heterosis for yield (as high as 11% over locations), may justify soybean hybrids as a breeding objective. However, the limited predictive value of CP and RFLP‐GS in our study indicates that the identification of favorable heterotic combinations may require extensive field testing.}, number={5}, journal={CROP SCIENCE}, author={ManjarrezSandoval, P and Carter, TE and Webb, DM and Burton, JW}, year={1997}, pages={1443–1452} } @article{bailey_mian_carter_ashley_boerma_1997, title={Pod dehiscence of soybean: Identification of quantitative trait loci}, volume={88}, ISSN={["0022-1503"]}, DOI={10.1093/oxfordjournals.jhered.a023075}, abstractNote={The dehiscence of pods (shattering) prior to harvest is an undesirable trait of soybean, Glycine max (L.) Merr. Pod dehiscence (PD) is relatively uncommon in modern North American soybean cultivars, but is often observed when unimproved germplasm or the wild species, G. soja Siebold & Zucc., are used as parents to introgress useful genes or to develop genetically diverse breeding populations. In light of the potential for efficient selection using DNA markers, the objective of this study was to identify quantitative trait loci (QTL) that condition resistance to PD. A map of 140 linked restriction fragment length polymorphism (RFLP) markers was constructed using 120 F4-derived lines from a soybean population (Young x PI 416937) that segregated for resistance to PD. These lines were scored for PD on a visual scale of 1 to 10 at both Athens, Georgia, and Windblow, North Carolina, in 1994. Heritability of pod dehiscence was 92%. Associations of marker loci with QTL that condition resistance to PD were tested using homozygous RFLP class means in a single-factor ANOVA. A total of five putatively independent RFLP markers were associated with PD at both locations and in a combined analysis over locations. A single RFLP locus on linkage group J of the USDA/Iowa State University map accounted for 44% of the variation in PD score. Epistasis was observed between one pair of significant marker loci. These results establish the genomic location of one major and a few minor QTL, identify an epistatic interaction, and indicate transgressive segregation which is plausibly the result of susceptibility alleles contributed by the resistant parent.}, number={2}, journal={JOURNAL OF HEREDITY}, author={Bailey, MA and Mian, MAR and Carter, TE and Ashley, DA and Boerma, HR}, year={1997}, pages={152–154} } @article{manjarrezsandoval_carter_webb_burton_1997, title={RFLP genetic similarity estimates and coefficient of parentage as genetic variance predictors for soybean yield}, volume={37}, ISSN={["1435-0653"]}, DOI={10.2135/cropsci1997.0011183X003700030002x}, abstractNote={RFLP genetic‐similarity estimates (RFLP‐GS) and coefficient of parentage (CP) have been used as measures of genetic similarity within crop species. However, practical application of these measures in plant breeding remains uncertain. This study was designed to probe the utility of RFLP‐GS and CP in predicting genetic variance (GV) for seed yield among inbred soybean [Glycine max (L.) Merr.] lines. achieve this goal, five single seed descent populations were studied, representing a range of RFLP‐GS and CP between the parents from 57 to 75% and 0.06 to 0.5, respectively. The GV for yield was estimated for each population through field evaluation of 30 inbred lines per population, in two North Carolina field locations during 1994. Both RFLP‐GS and CP correctly identified the population with the highest GV; however, CP predicted GV for yield more efficiently (rCP.RFLP‐GS = 0.91*; rCP.GV = −0.81*; and rRFLP‐GS.GV = −0,58). The GV was near zero when the CP between parents was larger than 0.27 or when RFLP‐GS was larger than 75%. Neither genotype × environment interaction nor low field precision were factors for the lower predictive value of RFLP‐GS. Expected gains from selection agreed partially with RFLP‐GS results but closely matched CP and the actual fate of populations in a USDA breeding program. These results indicated that caution should be taken in an applied soybean breeding program when crossing parents with a relationship larger than half‐sib or when the RFLP‐GS is larger than 75% when yield improvement is the main breeding objective.}, number={3}, journal={CROP SCIENCE}, author={ManjarrezSandoval, P and Carter, TE and Webb, DM and Burton, JW}, year={1997}, pages={698–703} } @article{carter_burton_bianchihall_farmer_huie_pantalone_1997, title={Registration of 'Graham' soybean}, volume={37}, ISSN={["1435-0653"]}, DOI={10.2135/cropsci1997.0011183X003700010064x}, abstractNote={Crop ScienceVolume 37, Issue 1 cropsci1997.0011183X003700010064x p. 293-294 Registration of Cultivars Registration of ‘Graham’ Soybean Thomas E.
