作者分别选用15个具不同毒性基因组合的叶锈菌系和10个具不同毒性基因组合的秆锈菌系推导分析了江苏省26个重要小麦品种(系)所携带的抗叶锈病和抗秆锈病基因。在供试的39个已知抗叶锈病基因(或基因组合)和44个已知抗秆锈病基因中,推导出了Lr1、Lr10、Lr13、Lr16、Lr26、Lt13+3Ka等6个抗叶锈病基因(或基因组合)和Sr5、Sr6、Sr7b、Sr8a、Sr9e、Sr10、Sr13、Sr14、Sr15、Sr17、Sr20、Sr23、Sr27、Sr28、Sr29、Sr31、SrTmp等17个抗秆锈病基因,以单基因或基因组合的形式分别分布在20和24个小麦品种(系)中,其中Lr16、Lr26和Sr5、Sr23、Sr31是供试材料的主要已知抗叶、秆锈病基因。初步发现一些品种(系)携带有Lr13和Sr31等已知持久抗锈基因(或基因组合)及不同于本研究所用的已知基因的未知基因。
In this paper, we selected 15 leaf rust strains with different combinations of virulence genes and 10 stromal rust strains with different combinations of virulence genes. The leaf rust resistance and anti-stalk resistance of 26 important wheat cultivars (lines) in Jiangsu Province were analyzed. Rust disease gene. Sixty-three leaf rust resistance genes, Lr1, Lr10, Lr13, Lr16, Lr26 and Lt13 + 3Ka, were deduced from 39 known leaf rust resistance genes (or gene combinations) and 44 known resistance stem rust genes Seventeen genes of rust resistance to rust were obtained from 17 genes including Sr5, Sr6, Sr7b, Sr8a, Sr9e, Sr10, Sr13, Sr14, Sr15, Sr17, Sr20, Sr23, Sr27, Sr28, Sr29, Sr31 and SrTmp. The genotypes or combinations of genes were distributed in 20 and 24 wheat cultivars (lines). Among them, Lr16, Lr26 and Sr5, Sr23 and Sr31 were the major known anti-leaf and stem rust genes of the tested materials. It was initially found that some cultivars (lines) carry known long-lasting anti-rust genes (or genogroups) such as Lr13 and Sr31 and unknown genes different from the known genes used in this study.
