摘要

为明确黄淮麦区小麦主栽品种抗条锈病基因组成,选用来自国内外的15个条锈菌菌株和21个以Avocet*S为遗传背景的小麦抗条锈病近等基因系,对我国黄淮麦区34个小麦主栽品种(系)进行苗期抗条锈病基因推导,并结合系谱分析明确其抗条锈病基因携带情况。结果表明,Yr3、Yr4、Yr8、Yr9、Yr17、Yr26、Yr27、Yr30、YrA、YrSp、YrSk分别以单基因或基因组合的形式存在于19个小麦品种中,Yr9比例最高,占29.4%,‘泰农18’等9份品种仅含一个抗条锈病基因,‘山农483’等10份品种含多个已知或未知基因,其余品种含有未知基因。该结果将为黄淮麦区小麦品种的合理布局提供依据。
        To understand the composition of yellow rust resistance genes(Yr genes) of 34 wheat cultivars in Huanghuai wheat growing region in China, a total of 15 stripe rust isolates and 21 stripe rust near-isogenic lines, which were under the background of Avocet*S, were selected from domestic and abroad, for genetic analysis of 34 wheat cultivars from Huanghuai wheat planting region. Integrated with the data, such as pedigree of cultivars(lines) and infection type patterns, the distribution of Yr genes was postulated. The results showed that a total of 11 Yr genes or gene combinations of Yr3, Yr4, Yr8, Yr9, Yr17, Yr26, Yr27, Yr30, YrA, YrSp and YrSk were postulated to be present in 19 wheat cultivars, and Yr9 gene was the most frequent(29.4%). Nine cultivars such as ‘Tainong18' contain single resistance gene, while 10 cultivars such as ‘Shannong483' contain multiple resistance genes. The other cultivars carried unknown Yr genes. The results will provide information for the reasonable distribution of wheat cultivars in Huanghuai wheat region.
