Abstract:
Longevity assessment of large number of genotypes takes longer time with traditional methods viz., germination tests throughout seed storage and identification of genotypes with higher longevity is crucial in developing new varieties with long storage life. Even though soybean is very sensitive crop very limited work has been carried out on seed longevity related traits. By analyzing 120 soybean genotypes, here we propose accelerated aging as simple and quick method to screen large number of soybean genotypes for longevity based on percent reduction in germination and study indicated that it is strongly correlated to longevity of genotypes and negatively impacted by seed weight, viz., bold seeds loose storability earlier than medium and small seeds. Seeds with grey hilum color has longer storability compared to others viz., black, brown, variegated and grey, yellow and these can be used as visual marker for longevity assessment. Thus, these simple ways can be employed for quick estimation and screening of large number of genotypes for longevity.
