摘要: 选用4个单交组合的亲本、F1、F2和F3,对普通小麦6个品质性状杂种早代的选择效果进行了研究。各品质性状遗传力偏中,蛋白质含量和面筋含量的遗传力均大于沉淀值的遗传力。各品质性状在杂种早期世代选择的相对预期遗传进度均较高,并且以沉淀值的为最高。在相关遗传进度的分析中,干面筋的选择对其他品质性状有较大的增效作用。

Abstract: With the parents F1,F2and F3 of 4 crosses,the effects of selection for six kernel quality characters in early generations in wheat were studied.The heritailities of the quality characters were in termiediate in which the heritabilities of the grain protein content and the gluten content were greater than that of the sedimentation value.The relative expected gain of selection for the quality characters in the early generations of all the studied crosses wash igh,and the sedimentation value was the greatest.In the analysis of correlated genetic gain,the selection for the dry gluten content had increasing effect on other quality characters.

Key words: Common wheat, Quality character, Heritability, Geneticgain, Selection
