| 摘 要： | 本文利用Clark和Harosoy成熟期等位基因系,研究了成熟期基因E_1e_1、E_2e_2、E_3e_3对出苗—开花、开花—成熟阶段以及全生育期的作用。E_1基因使出苗—开花延迟,但使开花—成熟阶段缩短,E_2和E_3使两个生育阶段都延长,以E_3的作用最小。成熟期基因具累加效应。延长生育期的显性基因使株高、主茎节数和分枝数增加,倒伏加重。但对每株荚数、单株粒重没有显著作用,对蛋白质和脂肪含量的影响也较小。

| Abstract: | Clark and Harosoy maturity isolines were used to study effect of maturity genes, E1e1, E2e2 and E3e3 on stages of emerging to flowering, flowering to maturity and emerging to maturity. Dominant gene E1 delayed stage of emerging to flowering, but shortened stage of flowering to maturity. E2 and E3 delayed both stages. Effect of gene E3 was weaker than others. Maturity gene effects were mainly additive. Dominant maturity genes also increased plant height, number of nodes on main stem, number of bernches and lodging, The effects of the genes on pod number per plant, seed weight per plant and 100-seed weight were not significant. The effects of the genes on protein contant and oil contant were slight |
