结荚习性是大豆的一个主要的形态性状,在育种上,已被国内外许多育种工作者所重视。Thseng与Hosokawa(1972)用不同结荚习性的大豆杂交,结果表明:全株荚数、主茎节数、主茎荚数、每株粒重等有明显的超显性现象,而结荚习性及其它性状只有部分显性。对于不同结荚习性品种杂交,其生育日数及早熟性的遗传研究较少。本试验的目的是研究不同结荚习性杂交对其后代生育期及产量因素的遗传关系,为培育早熟高产品种,正确地选配亲本提供科学依据。
Pods habitat is a major morphological trait of soybean, which has been valued by many breeders at home and abroad for breeding. Thseng and Hosokawa (1972) crossed with different heading habits of soybean, the results showed that: the whole plant pods, the number of main stems, the main stem pods, grain weight per plant and so significant over-dominant phenomenon, and the pod habit And other traits only partially dominant. There are few genetic studies on the days of birth and early maturity of hybrids with different pod habit. The purpose of this experiment is to study the genetic relationship of different sowing hybrids to their offspring growth and yield factors, and to provide a scientific basis for cultivating precocious and high-yielding varieties and correctly matching their parents.
