“…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).…”

“…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). The better quality maintained by the smaller soybean seeds may also be attributed to its ability to escape injury caused due to mechanical damage during harvesting, handling and processing (Robert, 1972).…”

“…The seed traits that enhances seed viability includes hard seed coat (Kumar et al, 2019a), small seed size (Hosamani et al 2013 ), black seed coat (Liu et al 2017) and tight attachment of the seed coat to the cotyledons (Kuchlan et al 2010). Typically wild type soybean seeds remain viable for longer duration than the cultivated type (Chandra et al 2017). Attempts have also been made to identify molecular markers linked to the traits considered to in uence viability traits (Dargahi et al 2014;Kumar et al 2019b;Zhang et al 2019).…”

Loss of seed viability is a serious hurdle in higher production and ambient seed storage of soybean. Understanding the factors affecting seed viability and identification 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 identified 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 significantly 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 identified in this study will serve as an elite soybean genetic resource in developing the soybean cultivars with better seed longevity.

“…The physical structure of the seed coat has great significance for seed longevity. The seed coat inhibits seed deterioration by preventing fungal and microbial attack (Chandra et al, ; Dang, Velusamy, & Park, ), whereas the coat also negatively affects seed germination rate by limiting water uptake (Kebede, Smith, & Ray, ). Different features of the seed coat play distinct roles in the regulation of seed longevity.…”

Both seed germination and early seedling establishment are important biological processes in a plant's lifecycle. Seed longevity is a key trait in agriculture, which directly influences seed germination and ultimately determines crop productivity and hence food security. Numerous studies have demonstrated that seed deterioration is regulated by complex interactions between diverse endogenous genetically controlled factors and exogenous environmental cues, including temperature, relative humidity, and oxygen partial pressure during seed storage. The endogenous factors, including the chlorophyll concentration, the structure of the seed coat, the balance of phytohormones, the concentration of reactive oxygen species, the integrity of nucleic acids and proteins and their associated repair systems, are also involved in the control of seed longevity. A precise understanding of the regulatory mechanisms underlying seed longevity is becoming a hot topic in plant molecular biology. In this review, we describe recent research into the regulation of seed longevity and the interactions between the various environmental and genetic factors. Based on this, the current state‐of‐play regarding seed longevity regulatory networks will be presented, particularly with respect to agricultural seed storage, and the research challenges to be faced in the future will be discussed.

“…It was reported that Arabidopsis thaliana has 5 structurally and functionally diverse ethylene receptors differing in their sequences and domains (Gallie, 2015). Seed coat permeability to silver ions across the genotypes is another factor that needs to be investigated (Salanenka and Taylor, 2011;Subhash et al, 2017). Detached leaves of the control plants were exposed to buffer only and fluorescence measured regularly.…”
