Screening of soybean [Glycine max (L.) Merrill] genotypes for seed longevity

Soybean seeds being inherently weak in structure is more susceptible to mechanical injury hence deteriorates faster and losses its seed quality so in the current research twenty one soybean genotypes were screened for seed longevity on the basis of standard germination test, methanol stress test and various morphological traits. Mean germination percentage of genotype after eight month of storage showed approximately the same germination after treating the freshly harvested soybean seeds with methanol. Germination percentage were found to be significantly negatively correlated with 100 seed weight, wrinkled seed coat, cracked seed coat percentage and positively with methanol stress test and smooth seed coat percentage. Bhatt. Kaliturr, TGX 1681-3F and PS 1225 were the best donors identified for longevity.
