In soybean, Glycine max (L.) Merr., substantial genetic variation exists for salt response. However, breeding for salt tolerance is hampered because no economically viable screening method has been developed for practical breeding. To facilitate the development of an effective screening method for salt tolerance in soybean, the present study was conducted to determine the heritability of salt tolerance and to identify associated quantitative trait loci (QTL). F2:5 lines from the cross of 'S-100' (salt tolerant) x 'Tokyo' (salt sensitive) were evaluated in a saline field in Hyde County, N.C., USA, in 1999 and in a greenhouse located in Raleigh, N.C., USA, in 2001. S-100 and Tokyo are ancestors of popular soybean cultivars released for the southern USA. The visual salt tolerance ratings of the F2:5 lines ranged from 0 (complete death) to 5 (normal healthy appearance). The entry-mean heritability for salt tolerance was 0.85, 0.48, and 0.57 in the field (four replications), greenhouse (two replications), and combined environments, respectively. The genotypic correlation between field and greenhouse ratings was 0.55, indicating reasonably good agreement between the two screening environments. To identify QTL associated with salt tolerance, each line was characterized with RFLP markers and an initial QTL single-factor analysis was completed. These results were used to identify genomic regions associated with the trait and to saturate the selected genomic regions with SSR markers to improve mapping precision. Subsequently, a major QTL for salt tolerance was discovered near the Sat_091 SSR marker on linkage group (LG) N, accounting for 41, 60, and 79% of the total genetic variation for salt tolerance in the field, greenhouse, and combined environments, respectively. The QTL allele associated with tolerance was derived from S-100. Pedigree tracking was used to examine the association between the salt tolerance QTL and flanking SSR marker alleles in U.S. cultivars descended from S-100 or Tokyo through 60 years of breeding. The presence of alleles from S-100 at the Sat_091 and Satt237 marker loci was always associated with salt tolerance in descendants. Alleles from Tokyo for these same markers were generally associated with salt sensitivity in descendent cultivars. The strong relationship between the SSR marker alleles and salt tolerance suggests that these markers could be used for marker-assisted selection in commercial breeding.}, number={8}, journal={THEORETICAL AND APPLIED GENETICS}, author={Lee, GJ and Boerma, HR and Villagarcia, MR and Zhou, X and Carter, TE and Li, Z and Gibbs, MO}, year={2004}, month={Nov}, pages={1610–1619} }

Merr.], but diversity of modern Japanese cultivars is not well characterized. The objectives of this study were to quantify genetic diversity of Japanese cultivars via coefficient of parentage (CP), determine the relative importance of breeding factors in explaining that diversity, and incorporate results into a practical guide for management of diversity. All 86 public Japanese cultivars released and registered during 1950 to 1988 were subjected to CP and multivariate analysis. The mean CP for the 86 cultivars was low (0.04), indicating a potentially high degree of diversity in Japanese breeding. Eighty percent of all pairs of cultivars were completely unrelated by pedigree. The low mean CP for the cultivars was attributed to a continual incorporation of unique Japanese land races into the genetic base over time, to the introduction of foreign germplasm from China and the United States and Canada (US-CAN) as breeding stock, and to limited exchange of germplasm among Japanese breeding programs. Cluster analysis was an effective discriminator of diversity. Six clusters were identified which had a mean CP value equivalent to that of half-sibs or greater. These clusters encompassed a total of 54 cultivars, explained 57% of the variation in the CP relations, and had few ancestors in common. Each cluster was derived primarily from only a few programs. Backcrossing and full-sib matings were absent in Japanese pedigrees and, thus, clusters were formed primarily from parent-offspring, full-sib, and half-sib relations. Cultivar attributes such as growing region, release era, maturity designation, and developing institution did not elucidate strong patterns of pedigree diversity. In practical breeding, one may maximize the chances of finding good specific Japanese × Japanese or Japanese × US-CAN crosses by choosing Japanese cultivars from a wide array of Japanese clusters rather than sampling extensively within a cluster.}, number={4}, journal={CROP SCIENCE}, author={Zhou, XG and Carter, TE and Cui, ZL and Miyazaki, S and Burton, JW}, year={2002}, pages={1331–1342} }

To characterize genetic diversity in applied breeding, plant breeders have invoked the concept of genetic base, which can be defined as the ancestral pool from which breeding is derived. The genetic base of modern Japanese soybean [Glycine max (L.) Merr.] cultivars is not well characterized. The objective of this study was to quantify the genetic base of Japanese soybean cultivars by coefficient of parentage (CP) analysis, to compare the genetic bases of major growing regions and release eras in Japan, and to compare the Japanese base with that of other countries. Seventy‐four ancestors were identified in the pedigrees of 86 public Japanese cultivars registered from 1950 to 1988. Ancestors originating from Japan contributed 76% of the genes to the Japanese breeding, while exotic ancestors from the USA and Canada (US‐CAN), China, and Korea contributed 2, 5, and 2%, respectively. The remaining portion of the base was of unknown, but presumed Japanese origin. Three major growing regions of Japan displayed very distinct genetic bases with at least 50% of the ancestral contribution unique to each region. Comparisons revealed that the Japanese base was more diverse than that of the US‐CAN. The more diverse genetic base was exemplified by (i) more ancestors accounting for 50 and 80% of the genes in Japanese breeding; (ii) a continual expansion of the genetic base since 1950, while the US‐CAN base remained relatively static; and (iii) a higher ratio of ancestors employed to cultivars released. The number of ancestors contributing to breeding in Japan was much smaller than that for China in terms of number of ancestors, even though both genetic bases expanded with time. The long history of soybean breeding in Japan, its diverse genetic base and its relative isolation from US‐CAN and China suggest that Japanese, Chinese, and North American breeding pools may serve as important reservoirs of diversity for each other. Twelve Japanese cultivars released from 1950 through 1988 derived at least 25% of their pedigree from improved U.S. or Chinese breeding materials.}, number={6}, journal={CROP SCIENCE}, author={Zhou, XL and Carter, TE and Cui, ZL and Miyazaki, S and Burton, JW}, year={2000}, pages={1794–1802} }

Koch) is classified as a secondary crop, i.e., derived from weeds of the primary cereal domesticates of the Near East. Avena sterilis L., the oldest hexaploid oat, is the putative progenitor of all other cultivated and wild hexaploid oat species. The objectives of this research were to gain insight into the origin of cultivated hexaploid oat by means of random amplified polymorphic DNA (RAPI)) marker variation and the distribution of the 7C‐17 intergenomic chromosomal translocation in cultivated and progenitor accessions. Cluster analyses based on 248 polymorphic RAPD markers found close association between several A. sterilis accessions from the Iran‐Iraq‐Turkey region and cultivated accessions. Genotypes within this group of cultivated and progenitor accessions were divided into those with the 7C‐17 translocation (A. sativa and A. sterilis) and those without the translocation (A. byzantina and A. sterilis). The results suggested that all cultivated hexaploids are derived from progenitor germplasm from Southwest Asia, present‐day Iran, Iraq, and Turkey. At least two paths of domestication occurred: one from A. sterilis with the translocation to A. sativa and one from A. sterilis without the translocation to A. byzantina.}, number={4}, journal={CROP SCIENCE}, author={Zhou, X and Jellen, EN and Murphy, JP}, year={1999}, pages={1208–1214} }
