| 摘 要： | 研究结果表明:春大豆秋播各性状的测量值变小,变异率依次为单株粒数>单株粒重和分枝荚数>分枝数>结荚节数>株高>单株荚数>每荚粒数>主茎节数>茎粗>主茎荚数>百粒重;亲本来源不同的组别间,以及亲本来源相同的不同株系间,上述性状的变异率存在较大差异;出苗至开花日平均温度直接影响单株产量,而且还通过株高、单株荚数和粒数间接影响单株产量。

| Abstract: | The result in this experiment showed that the ecological characters of spring soybean sowed in autumn were poorer than in spring sowing.The extent of characters variation was measured as follows:number of seeds on per plant>weight of seeds on per plant and number of pods on per branch> number of branches on per plant>number of nodes for pod on per plant>height of plant>number of pods on per plant>number of seeds on per pod>number of nodes on main stem>diameter of stem>number of pods on main stem> weight of 100-seed.There were large variation on ecological character between plant lines derived from differeuct parents and from same parents. The average day temperature from gemination to flowing not only direct affects the per plant yield in large extent but also plant hight, pods seeds on per plant indirect affects the per plnat yield. |
