在大豆轮回群体中根据熟期选择后,其下一群体成熟期间差异仍然十分明显而与上一轮相似。主要质量性状如茸毛色、叶形、茎色、花色等在早熟及晚熟群体中出现比率基本相同,表明质量性状的表现与熟期无关,熟期也不影响群体中不育株率。熟期影响数量性状的平均数及变异数,晚熟群体生物量、产量及其构成性状的平均数、变异数较早熟群体大。同一轮回世代中按熟期选择的未繁殖的亚群体性状表现并不完全符合这种规律。本文还对轮回群体用于研究性状间关系的作用进行了讨论。
The difference between the maturity stages of the next population in the soybean round-robin population is still significant, similar to the previous round, after maturity selection. The main quality traits such as velvet color, leaf shape, stem color, flower color appeared in the precocious and late-maturing groups were basically the same, indicating that the quality of the performance of the performance has nothing to do with maturity, maturity does not affect the population of sterile plant rate. The average number and variation of the quantitative traits affected by maturity, the average and the variation of the biomass, yield and its constituent traits of the late-maturing population were larger than that of the precocious population. The performance of unpublished sub-population traits selected by maturity in the same reincarnation does not fully comply with this law. The paper also discusses the role of reincarnation groups in studying the relationship between traits.
