摘要: 【目的】了解平安系列小麦品种(系)的穗发芽抗性及遗传组成。【方法】通过整穗发芽法对14个平安系列品种(系)的穗发芽特性进行分析,并用5个抗穗发芽基因的分子标记对穗发芽抗性基因来源进行检测。【结果】14个品种(系)中,平安11号相对穗发芽指数为0.19,达到抗穗发芽水平;平安658和平安701相对穗发芽指数分别为0.35和0.37,达到中抗穗发芽水平。抗穗发芽基因分子标记检测结果表明,TaPHS1基因在3个位点(-222、+646、+666)组成的单倍型相对穗发芽指数从低到高依次为CGAC<TGAC<TGAT<TATT,平安11号具有抗穗发芽能力最好的单倍型TaPHS1抗穗发芽基因,平安901等7个小麦品种(系)含有TaVp1B3抗穗发芽基因,平安12等4个小麦品种含有PM19A-1抗穗发芽基因,14个小麦品种(系)均不含Dorm-1和Tamyb10-D抗穗发芽基因。【结论】平安11号是唯一具有抗穗发芽单倍型CGAC的品种,可用于培育抗穗发芽小麦新品种和发掘抗穗发芽新基因。

Abstract: 【Objective】To investigate the pre-harvest sprouting resistance and genetic composition of Ping′an series wheat varieties(lines).【Methods】The pre-harvest sprouting characteristics of 14 Ping′an series varieties(lines) were analyzed by whole ear germination method,and the sources of pre-harvest sprouting resistance genes were detected by molecular markers of 5 anti pre-harvest sprouting genes.【Results】Among the 14 varieties(lines),the relative pre-harvest sprouting index of Ping′an No. 11 was 0.19,reached the level of resistance;the relative pre-harvest sprouting indexes of Ping′an 658 and Ping′an 701 were 0.35 and 0.37,respectively,reached the level of moderately resistance. The results of molecular marker detection of anti pre-harvest sprouting genes showed that the relative pre-harvest sprouting index of haplotype composed of three loci (-222、+646、+666) of TaPHS1 gene was CGAC<TGAC<TGAT<TATT from low to high,and Ping′an No. 11 contained the best haplotype of TaPHS1 gene of anti pre-harvest sprouting,7 wheat varieties(lines) including Ping′an 901 contained anti pre-harvest sprouting gene TaVp1B3,4 wheat varieties including Ping′an 12 contain anti pre-harvest sprouting gene PM19A-1,all 14 wheat varieties(lines) contain neither of anti pre-harvest sprouting gene Dorm-1 or Tamyb10-D.【Conclusion】Ping′an No. 11 is the only variety with hap-CGAC resistant to pre-harvest sprouting,which can be used in cultivating new varieties of anti pre-harvest sprouting wheat and discovering new anti pre-harvest sprouting gene.
