新引进小黑麦的醇溶蛋白遗传多样性分析

小黑麦作为黑麦中有益基因向小麦转移的桥梁,被广泛用于普通小麦的遗传改良．为了有效利用从国际玉米小麦改良中心引进的183份小黑麦材料,利用酸性聚丙烯酰胺凝胶电泳(A-PAGE)对其醇溶蛋白的遗传多样性进行了分析,结果表明：183份材料共分离出125种不同的带型,39条迁移率不同的谱带,其中只有在ω区的三条带为所有材料共有,其余的36条带都具有多态性,多态性带数占总分离条带数的92.3%,多态性较高；并且以中国春为对照,在小黑麦材料中没有发现与中国春的醇溶蛋白相同的谱带；通过醇溶蛋白的聚类分析可将183份小黑麦材料划分为三大类．

Genetic Diversity Analysis of Gliadin of Triticale Materials newly Introduced

Triticale has been used abroad in genetic improving of wheat as a bridge by which the available genes in triticale were transferred to wheat. In order to utilize the 183 triticale materials introduced from CIMMYT in effect, Genetic diversity analysis of gliadin of these materials was carried out by A-PAGE. It found that there are 125 different gliadin strap patterns and thirty-nine gliadin straps with different mobility separated among 183 triticale materials, among which, only three straps in w section are possessed by all the materials and the other thirty-six straps are of polymorpbic cbaracter The straps possessing polymorpbic character occupy 92.3 percent of the total separated straps and the polymorpbic character is bigh In comparison with the spring wheat, no same straps as spring wheat are found among triticale materials Based on cluster analysis of strap data, the 183 triticale materials can be divided into three groups.
