摘　　要：利用中美栽培品种Chrleston和东农594进行杂交,经多代自交,获得由143个株系组成的RILs（recombinant inbred lines）群体.以亲本和RIL群体为研究材料,分析了大豆生长过程中株高、主茎节数、主茎荚数、百粒重、蛋白质含量、脂肪含量的发育动态.结果表明：株高、主茎节数都呈逐渐增加的变化趋势,在8月6日左右接近最终值.主茎荚数呈先增加后降低的变化,在8月24日达到最大值,之后由于荚的脱落开始下降.百粒重的变化呈“S”形曲线,在开花后70 d接近最终重量.蛋白质含量呈先降后升的变化趋势,在开花后50～60 d达最低值,以后开始回升.脂肪含量持续增加,开花后70 d达最大值.One hundred and forty three recombinant inbred lines（RILs）derived from a cross between soybean cultivars Charleston and Dongnong 594 were used to study developmental performance of plant height,nodes on main stem, pods on main stem, 100-seed weight,protein content and oil content with growth of soybean plant in parents and RIL population. The results showed that plant height and nodes on main stem increased continuously and reached nearly final level after August 6. Pods on main stem increased quickly before August 24 and then declined owing to a- bortion of young pods. 100-seed weight had a increasing of ＂s＂ line and reached final weight 70 days after flowering. Protein content showed a decline-and-then-increase trend and got it＇s lowest point 50- 60 days after flowering. Oil content increased continuously and reached the highest level 70 days after flowering.
