Experiment was conducted to select soybean lines for having good storability and field germinability as compared to 3 soybean cultivar, i.e. NS 1, CM 60, and KUSL 20004. The cultivars, especially CM 60, lose their germination percentages easily. Data from an accelerated aging (AA) test of 95 soybean lines revealed that 30 lines were superior in terms of germination percentage, with the 100 seed weight well over 10 gm. These lines were compared with the above 3 cultivars for standard germination, seed moisture content, AA test, electrical conductivity of seed leachate in water, and AA test under controlled seed moisture and germinature temperature. Two lines were finally chosen to cross with the above 3 cultivars and select for soybean lines with high seed storability, high yield and yield components, and desirable agronomic characters.
