Evaluation of stripe rust resistance in 121 wheat cultivars and lines from Jiangsu Province
The objective of this study was to evaluate the resistance of 48 cultivars and 73 advanced lines from Jiangsu province to stripe rust.The results showed that Baokemai 1330,Suzhou 7906,Xuzhou 438,and Suyanmai 6231 exhibited moderate or high levels of resistance during the seedling stage.Thirteen cultivars,including Jili Mai,Nongmai 1,and Xuzhou 24,as well as 17 advanced lines,including Huaihe 12013,Jindi 166,and Wu 7815-5-2-1,showed moderate to high resistance levels in the four identification plots.Of these,Jili Mai,Nongmai 1,Xuzhou 24,and Huaihe 12013 demonstrated excellent resistance characteristics at the adult stage.There was a significant difference in the resistance performance among different identification plots.In Sichuan,the proportion of susceptible cultivars was higher.Consequenctly,future breeding programmes should prioritize the utilization of resistance sources against the pathogenicity of pathogens in the Southwest source base.
