“…Individually, these markers explained between 6.3 % (Satt285) and 7.5 % (Sat_434) of the total phenotypic variation for the trait (Singh et al 2008, Table 1). Specific bands produced by SSR markers Satt371, Satt453 and Satt618 make them candidate markers for linkage with seed storability and testa colour (Hosamani et al 2013). The last decade has also seen research directed towards the inference of the genetic basis of seed deterioration through investigation of quantitative trait loci associated with seed longevity (Han et al 2014).…”

Soybean is an economically important leguminous crop. Genetic improvements of soybeans have focused on enhancement of seed and oil yield, development of varieties suited to different cropping systems, and breeding resistant/tolerant varieties for various biotic and abiotic stresses. Plant breeders have used conventional breeding techniques for the improvement of these traits in soybean. The conventional breeding process can be greatly accelerated through the application of molecular and genomic approaches. Molecular markers have proved to be a new tool in soybean breeding by enhancing selection efficiency in a rapid and time-bound manner. An overview of molecular approaches for the genetic improvement of soybean seed quality parameters, considering recent applications of marker-assisted selection and 'omics' research, is provided in this article.

“…However, in most of the 'seed vigor' literature for soybean, total germination proportion is the only/major trait determined [16][17][18][19]. In addition, weak correlations between germination ability and seedling performance were often found in the investigation of seed vigor [59][60][61], though the germination rate appeared to be closely associated with seedling-related traits (R 2 > 0.5) in some research [13,18].…”

“…Genetic mapping is an effective approach to identify genomic regions and functional variations in genes controlling a given trait in crops [54,80]. So far, there have been 18 seed vigor-related QTLs detected in soybean, and no common QTL was found among the different research populations [17][18][19]. Due to technical limitations, information regarding candidate genes near/within the identified SSR markers/QTL intervals was missing in the earlier mapping studies.…”

“…The use of molecular markers has provided insights into the genomic location and gene action of quantitative trait loci (QTLs) for seed vigor during soybean storage. Up to the present, 18 QTLs associated with seed vigor have been identified on 15 chromosomes using different soybean populations [16][17][18][19]. According to the germination percentage of F 2:3 progenies from 'Birsa soya-1' (black-seeded variety with long lifespan) and 'JS71-05' (yellow-seeded variety with short longevity) subjected to accelerated aging (AA) tests in the laboratory, Singh et al [20] detected four SSR markers (Satt600, Satt538, Satt434, and Satt285 located on chromosome 2, 8, 12, and 16, respectively) associated with seed vigor.…”

In addition, based on the seed germination performance of 33 soybean genotypes under ambient and AA storages, three SSR markers (Satt371, Satt453, and Satt618) were identified for linkage with both seed vigor and seed coat color [19]. Dargahi et al [17] mapped three independent QTLs on chromosomes 4, 13, and 19 via the relative germination rate in the F 3 and F 4 populations from a cross between 'MJ0004-6' with poor longevity and 'R18500' with good longevity, but a common QTL for seed vigor was missing from the seeds produced in different years.…”

Due to its fast deterioration, soybean (Glycine max L.) has an inherently poor seed vigor. Vigor loss occurring during storage is one of the main obstacles to soybean production in the tropics. To analyze the genetic background of seed vigor, soybean seeds of a recombinant inbred line (RIL) population derived from the cross between Zhonghuang24 (ZH24, low vigor cultivar) and Huaxia3hao (HX3, vigorous cultivar) were utilized to identify the quantitative trait loci (QTLs) underlying the seed vigor under −20 °C conservation and accelerated aging conditions. According to the linkage analysis, multiple seed vigor-related QTLs were identified under both −20 °C and accelerated aging storage. Two major QTLs and eight QTL hotspots localized on chromosomes 3, 6, 9, 11, 15, 16, 17, and 19 were detected that were associated with seed vigor across two storage conditions. The indicators of seed vigor did not correlate well between the two aging treatments, and no common QTLs were detected in RIL populations stored in two conditions. These results indicated that deterioration under accelerated aging conditions was not reflective of natural aging at −20 °C. Additionally, we suggest 15 promising candidate genes that could possibly determine the seed vigor in soybeans, which would help explore the mechanisms responsible for maintaining high seed vigor.

Loss of seed viability is a serious hurdle in higher production and ambient seed storage of soybean. Understanding the factors affecting seed viability and identi cation of soybean genotype(s) with higher viability is critical for higher soybean production. In this study, seeds of 125 soybean genotypes of three different species (Glycine tomentella, Glycine soja and Glycine max) and 25 RILs (Glycine soja × Glycine soja) were tested for germination immediately after harvest followed by one, two and three years of ambient storage. Fresh seeds of all the genotypes recorded 78-99% germination with a mean of 94.02%. However, the mean value of per cent germination of all the genotypes after one, two and three years of ambient storage decreased and found to stand at 79.51%, 52.24% and 29.18%, respectively. Among the genotypes tested, G. tomentella accession registered highest seed storability followed by G. soja, RILs and G. max. After three years of storage, 14 wild type genotypes and 3 RILs maintained >70% germination and identi ed as 'good storers'. Genetic divergence studies via k-mean clustering and principal component analysis grouped all genotypes in three cluster/component based on seed size, seed coat permeability and seed viability. Seed viability was signi cantly and negatively correlated with electrical conductivity. Good storers found to be having slow imbibition rate than poor storers in initial hours of imbibition. The good storing genotypes identi ed in this study will serve as an elite soybean genetic resource in developing the soybean cultivars with better seed longevity.
