“…The seed coat permeability found to have negative correlation with seed viability, which is in agreement with Nacer et al ( 2017) and Kumar et al (2019a). The seed size has positive correlation with mechanical damage and seed coat permeability (Mugnisjah et al 1987;Chandra et al 2017) and negative correlation with seed viability (Tiwari and Joshi 1989;Kumar et al 2019a). The larger seeds found to have more seed coat permeability (Chandra et al 2017).…”

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.

“…Differences in the storage potential of cultivars within a species have also been reported in grain legumes as being associated with seed-coat pigmentation. To corroborate with this assertion, the findings of Asiedu and Powell (1998) in Cowpea (Vigna unguiculata L. (Walp)), Abdullah et al (1993) in Phaseolus vulgaris and Mugnisjah et al (1987) in soybean, reported that soybean cultivars having unpigmented seed coats deteriorated more rapidly during storage than cultivars with pigmented seed coats. In the present study however, all cowpea varieties had light coloured or unpigmented seed coat.…”

<p>This study was set to investigate the germinability and storability of the newly released cowpea genotypes and secondly the influence of different storage materials under ambient storage condition on seed vigour and germination over time. The experiment was laid in a Split-split plot design with four replicates. The main plot was duration (0, 30, 60 and 90 days), while Storage material (polyethylene bag, cotton bag and glass container) was sub plot and the four cowpea genotypes were sub-sub plot. Results from the study showed that irrespective of the cowpea genotypes and storage material used, percentage vigour and germination were significantly affected with time in storage. Seeds stored in cotton bags had the least percentage vigour (57%) and germination (65%) while the highest was recorded for seeds stored in air-tight glass containers. Among all the cowpea genotypes studied, Hewale was found to have poor storage abilities. For better storage of cowpea seeds for a period exceeding 3 months, it is preferable to use glass containers or black polyethylene bags even under ambient condition to maintain seed vigour and germinability.</p>

“…These results were in accordance with earlier work of Kumar (2005) and Sooganna (2015) in soybean. Further, black seed coat is also associated with resistance to field weathering (Mugnisjah et al, 1987) and better resistance against pathogen (Starzinger and West, 1982) and hence, is classified as a better storer. Better physiological quality of genotypes with black coats as compared to genotypes with yellow coats was also reported by Bahry et al 2017 in soybean.…”

Background: The soybean seed is highly susceptible to field weathering and mechanical damages which adversely affect its longevity. Non-availability of good quality seed and post-harvest maintenance of prescribed level of seed germination and vigour until immediate planting season is the major constraint for soybean seed production. In soybean, the seed coat is one of the main determinants of seed germination, vigour and longevity potentials. Methods: In view of the same, the present study was conducted during 2015-16 and 2016-17 on 24 soybean genotypes having contrasting seed longevity traits. Freshly harvested seeds were stored for eight months under laboratory ambient environment (25±2°C and 65±5% RH) for evaluation of seed coat properties which are helpful in protecting the seeds from mechanical damage during pre- and post-harvest operations and study its relation with the seed quality. Result: Black, small-seeded soybean genotypes with white hilum were found to be better storers. Thick seed coat and higher seed coat (%) with more and uniform hours glass cells attributed to better seed quality for these genotypes. Parameters like seed coat (%), lignin content and mechanical strength remained unchanged during eight months laboratory ambient storage. Based on these observations, genotypes AMSS-34 and G-2265 were identified as better genotypes, which may be exploited in soybean crop improvement programme.
