Characterization of Soybean Varieties for their Storage Potential by Using Accelerated Ageing

Soybean being a potential oil and protein crop for narrowing the oil and nutrition gap, occupies an important place in agricultural economy of India. The seed of soybean varieties PS 1347, PS 1042, PK 472 and PK 262, obtained from Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar were used for this study. Electrical conductivity increases while germination percent, seedling length and seedling vigour index-I decreases with an increase in accelerated aging periods in all varieties. Increase in electrical conductivity was minimum in PS 1042 and followed by PS 1347. Decrease in germination percent, seedling length and seedling vigour index-I was less in PS 1042 followed by PS 1042. Varieties PK 472 and PK 262 were found same in all studied parameters. This indicate that PS 1042 show better membrane integrity followed by PS 1347 thus have better storability than rest of the varieties.
