摘要
在北京生态条件下,选取生育期在100 d以内的我国南方及国外38个大豆品种,进行生育期结构与农艺性状遗传变异方面的研究,试验结果表明:遗传力较高的有大豆主茎分枝始节R。、生育前期、全生育期、荚长、主茎节数、主茎分枝数、单株粒数。筛选出一批对光温反应不敏感、早熟、高产大豆品种。
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.
