对从蓝糊粉层大麦品种义乌二棱诱变而来的两个无原花色素突变体义ａｎｔ９０－１和义ａｎｔ９０－２进行杂交后代籽粒原花色素和蓝糊粉层性状的分析，探明了原花色素缺失突变基因ａｎｔ对蓝糊粉层表达的控制作用。试验结果表明，不同ａｎｔ基因位点对蓝糊粉层表达的影响不同，这决定于其在色素物质生物合成途中所控制的反应步位，某些ａｎｔ位点如ａｎｔ１３、ａｎｔ１８、ａｎｔ２１、ａｎｔ２２等与蓝糊粉层基因（Ｂｌ′ｓ）有互补效应，只要这些基因之一处于隐性纯合时，就表现为白糊粉层。供试突变体义ａｎｔ９０－２与ａｎｔ１３等位，故其本身既表现为无原花色素，又表现为白糊粉层。义ａｎｔ９０－１中的ａｎｔ突变位点与蓝糊粉层基因无互补效应，其本身表现为无原花色素和蓝糊粉层。
Analysis of the proanthocyanidin and blue ale powder traits of two proanthocyanidin-derived ant90-1 and ant90-2 mutants derived from the blue barley-derived barley variety Yiwu Erliu Understand the control of pro-anthocyanidin-deficient mutant gene ant on the blue ale powder layer. The results showed that different ant loci had different effects on the expression of bluerit starch layer, which was determined by the reaction steps controlled by the pigment biosynthesis pathway. Some ant sites such as ant13, ant18, ant21, ant22, etc. Has a complementary effect with Bl’s, and as long as one of these genes is recessive homozygous, it behaves as a white aleurone. The test mutants rightest ant90-2 and ant13 allele, it is not only manifested as proanthocyanidin, but also as white aleurone. Ant ant90-1 ant mutation sites and bluerone layer gene no complementary effect, its performance is free of proanthocyanidin and blue aleurone layer.
