“…Similarly, seed coat permeability appeared to be negatively correlated with seed viability (Table 2). Similar findings were reported by Singh et al (2008) and Adsul et al (2018). However, exception does exist.…”

Soybean seeds loss viability very rapidly during ambient storage in the tropical and sub-tropical environments. In this study, interrelationship between seed coat permeability and viability over periods of ambient storage was assessed using a set of 217 recombinant inbred lines (RIL) developed from an inter-specific cross between wild type (Glycine soja) accession DC2008-1 and cultivated (G. max) variety DS9712. G. soja seeds were tiny, black, impermeable and highly viable while G. max seeds were large, yellow, permeable and poorly viable during ambient storage. Seed coat permeability and viability of the fresh, one-year and two-year-stored seeds (stored in room temperature, av. 25±2°C and 65±5% RH) were tested as per standard protocols in completely randomized design with two replications. Significant variation was found among genotypes for the seed viability, permeability, periods of storage and their interactions. Permeability of the seed coat increased with the period of storage. In the fresh, one-year and two-yearstored seeds, the seed coat permeability was 62.87, 75.17 and 90.52%, respectively. Viability of the seeds was negatively correlated with period of storage and seed size. In the fresh, one-year and two-year-stored seeds, average viability was 90.7, 75.6 and 54.1%, respectively. Scanning electron microscopy (SEM) indicated presence of intact hilum, strong hourglass cells and non-cracked seed coat in the highly viable seeds. A set of 24 RILs were found that maintained higher viability (>80%) with varying degree of permeability after two years of storage. Among the highly viable RILs, more were black seeded. RIL Nos. 7-12-3, 7-24- 1, 13-2-2, 13-31-4 found to maintain both viability and permeability in higher order during storage and would pave the way for development of soybean genotypes with high viability and permeability.

“…It is found to be the cheapest source of vegetable oil, and protein. Considering the power, properties and limitless applications, the soybean has been christened as the 'Golden bean' (Adsul et al 2018). However, viability of the soybean seed is a serious concern for the farmers and traders; it rapidly loses viability during ambient storage more severely in the tropic and sub-tropics (Hang et al 2015), which severely affects seedling vigour, crop stand in the eld and eventual yield.…”

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.

“…Seed longevity is defined as the ability of a seed to remain viable during storage. Over time, seed viability gradually decreases because of aging or deterioration events, which eventually result in poor seedling establishment (Adsul et al 2018). Seeds with extended longevity are intact and produce vigorous seedlings, which ultimately ensures a high yield.…”

The mature embryos of rice seeds contain translatable mRNAs required for the initial phase of germination. To clarify the relationship between seed longevity and RNA integrity in embryos, germinability and stability of embryonic RNAs were analyzed using the seeds of japonica rice cultivars subjected to controlled deterioration treatment (CDT) or long periods of storage. Degradation of RNA from embryos of a japonica rice cultivar "Nipponbare" was induced by CDT before the decline of the germination rate and we observed a positive relationship between seed germinability and integrity of embryonic RNAs. Moreover, this relationship was confirmed in the experiments using aged seeds from the "Nipponbare", "Sasanishiki" and "Koshihikari" rice cultivars. In addition, the RNA integrity number (RIN) values, calculated using electrophoresis data and Agilent Bioanalyzer software, had a positive correlation with germinability (R 2 =0.75). Therefore, the stability of embryonic RNAs required for germination is involved in maintaining seed longevity over time and RIN values can serve as a quantitative indicator to evaluate germinability in rice.
