本文对4个栽培大豆与半野生大豆杂交组合后代进行了遗传分析。结果表明:除百粒重外,杂种F_1代各农艺性状优势表现普遍存在。F_2代性状分离广泛,类型丰富,出现了大量超亲植株。株高、主茎节数、百粒重、茎粗、一荚粒数遗传力较高。单株粒重、单株粒数、单株荚数、每节荚数遗传力居中,分枝数最低。各性状的遗传进度绝对值都比较大,选择效果明显。半野生大豆利用应予以重视。
In this paper, four cultivated soybean and semi-wild soybean cross combinations of genetic analysis. The results showed that in addition to the 100-grain weight, F1 performance of agronomic traits of hybrid F1 widespread. F_2 generations of traits widely separated, rich in type, there have been a large number of super-progeny plants. Plant height, the number of main stems, a hundred weight, stem diameter, a pod grain number heritability higher. Grain weight per plant, grain number per plant, number of pods per plant, the heritability of each pod was middle, and the number of branches was the lowest. The genetic progress of all traits are relatively large absolute value, the selection effect is obvious. Semi-wild soybean should be taken seriously.
