摘要: 选用3个南农系列菜用大豆新品种(系),对其荚粒品质发育特性进行研究,结果表明:荚的外形(长、宽、厚)发育呈"S"型生长曲线;百粒鲜质量和青籽粒可溶性糖含量的积累过程可用三次方程模拟;兼顾产量、品质确定最佳采摘期为满粒(R6)后期~初熟(R7)前期。在此基础上,应用植物数量性状主基因+多基因分离分析法对南农95C-7×南农95C-15杂交组合4个世代群体可溶性糖、淀粉含量进行联合分析,结果表明:两个性状均属于两对主基因控制,同时存在多基因修饰作用,其中主基因遗传率均高,分别为85.8%,77.4%,多基因遗传率相对较低,分别为12.3%、12.7%。

Abstract: Abstract:Three vegetable soybean cultivars, NAU95C-7, NAU99-10 and NAU95C-15, were used to study the developmental process of pod and seed qualities. The results showed as follows: The changes of pod form, such as length, width and thickness, with the days after flowering were well fitted with 'S' curve; the accumulations of 100-seed fresh mass and soluble sugar content with the days after flowering were well fitted with cubic equation; the suitable pod-picking period was suggested as during later-term R6 to former-term R7 on the basis of yield and quality. Then, with the major gene plus polygene model of quantitative traits, a joint analysis of multi-generations from the cross between NAU95C-7 and NAU95C-15 was carried out to investigate the inheritance of the soluble sugar and starch content. The results showed that the inheritance of two characters fitted two major genes plus polygene model. Heritability values of the major genes of F2 population were estimated as 85.8%,77.4% respectively, while those polygene were 12.3%, 12.7% respectively.
