| In order to understand the disease resistance status of the main wheat cultivars in Sichuan Province,and popularize wheat varieties with good multiple resistance,153 wheat varieties(lines) in Sichuan Province were selected as materials. The resistance identification of different materials in two wheat growth cycles was carried out in 2018－2019 and 2019-2020 by using the method of inoculation induced identification of stripe rust. Meanwhile,the molecular markers of mapped genes Yr5 , Yr9 , Yr10 , Yr15 , Yr18 , Yr26 , Pm21 and Fhb1 were used to detect the type of wheat disease resistance genes which consist of stripe rust resistance gene,Fusarium head blight resistance gene and powdery mildew resistance gene. The results show that among the tested 153 wheat materials at adult stage,122 materials showed medium resistance or above to stripe rust,accounting for 79.7% of the tested materials. The results of gene molecular marker analysis showed that there are 12,25,77,12,4 and 90 wheat varieties(lines) carrying stripe rust resistance genes: Yr5 , Yr9 , Yr10 , Yr15 , Yr18 and Yr26 ,accounting for 7.8%,16.3%,50.3%,7.8%,2.6% and 58.8%,respectively; 40 wheat varieties(lines) carry powdery mildew resistance gene Pm21 ,accounting for 26.1%;12 wheat varieties(lines) carry Fusarium head blight resistance gene Fhb1 ,accounting for 7.8%; yet 15 wheat materials carry no resistance genes in this study. |
