Gliadin and glutenin electrophoresis of F2 progeny from four crosses of durum wheat was used to analyse the linkage relationships between prolamin genes on chromosomes 1A and 1B. The results showed that these genes are located at the homoeoallelic lociGlu-1,Gli-3,Glu-3 andGli-1. The genetic distances between these loci were calculated more precisely than had been done previously for chromosome 1B, and the genetic distances betweenGli-A3,Glu-A3 andGli-A1 on chromosome 1A were also determined. Genes atGli-B3 were found to control someω-gliadins and one B-LMW glutenin, indicating that it could be a complex locus.
利用来自四个硬质小麦杂交后代的 F2 群体进行醇溶蛋白电泳分析,研究了染色体 1A 和 1B 上 prolamin 基因之间的连锁关系。结果表明,这些基因位于同源等位基因座位 Glu-1、Gli-3、Glu-3 和 Gli-1 上。与以前对 1B 染色体的研究相比,这些座位之间的遗传距离得到了更精确的计算,并且还确定了 1A 染色体上 Gli-A3、Glu-A3 和 Gli-A1 之间的遗传距离。发现 Gli-B3 上的基因控制着一些ω-醇溶蛋白和一个 B-低分子量麦谷蛋白,表明它可能是一个复杂的基因座。
