| Abstract: | The studies on the bearing term structure and the genetic variation of agronomic characters of 38 varieties from southern or abroad which bearing term was less than 100 days in the condition of Beijing ecosystem. The results indicated the first node of caulis'divarications,R1 .bearing term prophase, whole bearing term, the length of legume, the number of caulis' node, the number of caulis' divaricating and the amount of seeds per plant are all in high h2. Screen out the soybean varieties which insensitive to light and temperature, precocity, high yield. |
