以三个冬小麦单交组合为试验材料,采用遗传力、遗传进度和杂种后代品质性状表现在年份间的稳定性等分析方法,对小麦几种品质性状与产量性状早代选择的效果进行了研究.结果表明,沉淀值、容重的遗传力较高,蛋白质含量和单株蛋白质产量的遗传力较低.沉淀值、蛋白质产量在各杂种早代的相对预期遗传进度均在20%以上.不同的品质性状受环境的影响较大,但所表现出的稳定性不同.
Three single winter wheat combinations were used as experimental materials to study the effects of the stability, inheritance, genetic progress and quality trait of hybrid progeny between years on the selection of several quality traits and yield traits in wheat The results showed that the hereditary value of sedimentation value and bulk density was higher, and the heritability of protein content and protein yield per plant was lower.The relative expected genetic progress of sedimentation value and protein yield in all hybrids was more than 20% Quality traits are more affected by the environment but show different stability.
