几个外省冬小麦亲本产量性状遗传力和配合力分析

几个外省冬小麦亲本产量性状遗传力和配合力分析摘要：小麦在我国有着重要的地位，小麦是我国主要的粮食作物之一，为了选育出优良的小麦品种，进一步研究其遗传力与配合力，选用中信麦 98、JX-11、LXH-1、汝麦 076、良星 517、济麦 22、青麦 6 号、泰农 18、XX-14-2 为研究亲本，做出了5×4 的 20 个杂交组合，并对杂交后代的的一些性状进行观测。并对这些性状的配合力进行了计算与分析。将所得的数据罗列出来，进行详细的研究。我们在试验中发现，泰农 18 是所有性状都比较优异的亲本，它的一般配合力都挺高。再者汝麦 076 和 LXH-1 是可以用来提高小麦的千粒重。本次的试验结果显示：JX-11×泰农 18、汝麦 076×XX-14-2、良星 517×泰农 18 这几个组合可以用来当高产量育种的亲本材料。关键词：方差；遗传力；效应值；杂交本Analysis of heritability and combining ability of yield characters in wheat parentsAbstracts:Wheat plays an important role in our country. Wheat is one of the main food crops in our country. In order to select excellent wheat varieties and further study their heritability and combining ability, 20 hybrid combinations of 5 × 4 were made with zhongxinmai 98, jx-11, lxh-1, Rumai 076, Liangxing 517, Jimai 22, Qingmai 6, Tainong 18, xx-14-2 as the parents Some characters were observed. The combining ability of these characters was calculated and analyzed. The data are listed and studied in detail. In our experiment, we found that Tainong 18 is a parent with excellent characters, and its general combining ability is very high. Moreover, Ru Mai 076 and lxh-1 can be used to increase the 1000 grain weight of wheat. The results showed that JX-11 × Tainong 18, Rumai 076 × XX-14-2 and Liangxing 517 × Tainong 18 could be used as parents for high yield breeding.Key words：Variance; heritability; effect value; hybrid1.绪论：小麦是中国乃至世界的主要粮食之一，相比较普通的小麦品种，良种小麦的适应性、产量、抗病能力等方面有着显著的又...
