摘要: 为了明确光周期基因显隐性组成在我国小麦品种中的分布情况,利用小麦光周期基因 Ppd-A1Ppd-B1 Ppd-D1 的STS分子标记,对我国180份小麦品种进行分子标记检测。结果显示,所有供试材料在B1位点均检测为隐性 Ppd-B1b 。在A1位点,仅有扬麦11品种检测为显性 Ppd-A1a (0.6%),其余检测材料均为隐性 Ppd-A1b;在D1位点,有5份材料检测为隐性,其余175份材料检测均为显性 Ppd-D1a (97.2%)。对所有材料进行基因型统计分析,发现我国品种主要存在 Ppd-A1b/Ppd-B1b/Ppd-D1bPpd-A1b/Ppd-B1b/Ppd-D1aPpd-A1a/Ppd-B1b/Ppd-D1a 几种基因型。 研究结果表明,我国小麦品种的光周期不敏感特性主要是 Ppd-D1 位点的变异,在 Ppd-A1Ppd-B1 位点的变异较少。

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 marker of Ppd-A1, Ppd-B1 or Ppd-D1.The results showed that no dominant allele of Ppd-B1 was found in the wheat cultivars 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 decideded by Ppd-D1a,and the mutations were less in Ppd-A1 and Ppd-B1 loci.
