光周期基因在我国小麦品种中的多态性分布
The Polymorphism Distribution of the Photoperiod Genes in Wheat Varieties in China
摘要
Abstract
In order to identify the distribution characteristics of the allelic composition of the photoperiod genes in wheat cultivars of China ,the photoperiod genes of 180 Chinese wheat cultivars were analyzed using the STS mark-er of Ppd-A1,Ppd-B1 or Ppd-D1.The results showed that no dominant allele of Ppd-B1 was found in the wheat cul-tivars in this study.For Ppd-A1,all cultivars were recessive (99.4%) among wheat cultivars except Yangmai 11. For Ppd-D1,5 cultivars were recessive and the rest of 175 cultivars (97.2%) were dominant.The statistics analysis of photoperiod genotypes showed that the study found three genotypes of photoperiod -insensitive alleles in all the tested materials, namely Ppd-A1b/Ppd-B1b/Ppd-D1b, Ppd-A1b/Ppd-B1b/Ppd-D1a and Ppd-A1a/Ppd-B1b/Ppd-D1a.The results of the study indicated that the photoperiod-insensitivity of wheat varieties in China was mainly de-cideded by Ppd-D1a,and the mutations were less in Ppd-A1and Ppd-B1 loci.关键词
