“川麦42”和“川麦43”是源于CIMMYT硬粒小麦-节节麦人工合成种的姊妹系,具有高产、高抗条锈等特征。本实验利用小麦A、B、D基因组上的91对引物对“川麦42”和“川麦43”进行了SSR分子标记比较分析。结果表明,分析的91个SSR标记位点中有61个位点“川麦42”与“川麦43”多态性一致,占位点数的67.03%;有30个位点两个品种存在多态性差异,占位点数的32.97%;30个差异位点在A、B和D三个基因组的分布频率(占该基因组被检测位点数)不一致,其中A基因组分布最多,B基因组分布最少,其顺序为A>D>B。
“Chuanmai 42” and “Chuanmai 43” are the sister lines derived from CIMMYT durum - Artemia nodosum with high yield and high resistance to stripe rust. In this experiment, 91 pairs of primers were used to analyze Chuanmai 42 and Chuanmai 43 by SSR markers in wheat A, B and D genomes. The results showed that 61 loci of 91 SSR markers were consistent with “Chuanmai 43” polymorphic loci, accounting for 67.03% of the loci; there were more loci in 30 loci Which accounted for 32.97% of the total number of loci. The distribution frequencies of the 30 differential loci in A, B and D genomes (accounting for the number of detected loci in the genome) were not consistent. Among them, A was the most abundant and B was the least, The order is A> D> B.
