小麦骨干亲本周8425B衍生品种(系)春化和光周期基因的组成分析
Composition Analysis of Vernalization and Photoperiod Genes in Varieties(lines)Derived from Core Wheat Parent Zhou 8425B
摘要
Abstract
The distribution,combination types of photoperiod and vernalization genes in 219 materials[core wheat parent Zhou 8425B and its derived varieties(lines)]were detected using functional markers of vernalization genes(Vrn-A1,Vrn-B1 and Vrn-D1)and photoperiod genes(Ppd-A1,Ppd-B1 and Ppd-D1),and their effects on yield-related traits were studied.The results indicated that the distribution frequencies of dominant vernalization genes of Vrn-A1,Vrn-B1 and Vrn-D1 were 0,1.37%and 25.11%in 219 materials,respectively.There were three types of vernalization gene combinations in 219 materials,including vrn-A1+vrn-B1+vrn-D1,vrn-A1+vrn-B1+Vrn-D1 and vrn-A1+Vrn-B1+vrn-D1,among which vrn-A1+vrn-B1+vrn-D1 had the highest distribution frequency of 73.52%,and vrn-A1+Vrn-B1+vrn-D1 had the lowest distribution frequency of 1.37%,indicating that most of the 219 materials were winter wheat.All varieties(lines)contained the photoperiod insensitive genes Ppd-A1a,Ppd-B1a and Ppd-D1a.The vrn-A1+vrn-B1+vrn-D1 combination had the highest yield,1 000-grain weight and the shortest plant height;The vrn-A1+Vrn-B1+vrn-D1 combination had the lowest yield,1 000-grain weight and the tallest plant height;The vrn-A1+vrn-B1+Vrn-D1 combination was middle.This indicates that the recessive vernalization gene combination has the highest yield,1 000-grain weight and the shortest plant height;When the vernalization gene combination contains a dominant allele,the plant height increases,and the 1 000-grain weight and yield decrease.关键词
