【摘要】 利用p×q交配模式分析了小麦产量和品质性状在杂种F₁的表现和配合力。结果表明,品质性状在F₁多倾低亲或近中亲遗传,呈负向优势,产量性状则表现较大的正向优势。各性状的基因效应以加性为主。#409在品质性状上一般配合力较高,小偃6号和冀麦23则在产量、千粒重及蛋白质产量等性状上表现优良。更多还原

【Abstract】 The heterosis and combining ability of wheat yield and quality characters in F1 were analysed with p×q cross model. The results indicated that the inheritance of most qualitics in F1 tended low parent or near middle parents, and negative superiority, and the inheritance of yield characters tended positive superiority. Most of characters were mainly controlled by additive genes. General combining ability of Jing 409 in quality character was higher than other varieties. The characters of yield, 1000-kernel weight and protein yield etc of xiao yan 6 and number Jimai 23 were good.更多还原
