Variances for Several Agronomic Traits and Interrelationships among Characters of Introduced Soybean Varieties Grown in Korea

This investigation was conducted to evaluate various agronomic characters of soybean varieties introduced from U.S.A., Japan, Taiwan and Vietnam. The yields of introduced varieties were ranged from 1292 kg/ha to 129 kg/ha. This result indicates that introduced varieties were not extremely superior over local varieties (18 major varieties) tested under identical environment. Whereas, some varieties possess definitely superior characters in plant height, number of nodes, number of podes, number of branches, and maturity. Since no varieties possessing high yield with high protein were found in this investigation, extensive gene source collection has to be practiced.
