Identification of Stripe Rust Resistance Genes in Common Wheat Cultivars From the Huang-Huai-Hai Region of China

Wheat stripe (yellow) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a serious fungal disease worldwide, especially in the Huang-Huai-Hai region, a main wheat production area in China. Gene postulation, molecular testing, and pedigree analysis were conducted to determine the presence...

520 |a Wheat stripe (yellow) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a serious fungal disease worldwide, especially in the Huang-Huai-Hai region, a main wheat production area in China. Gene postulation, molecular testing, and pedigree analysis were conducted to determine the presence of stripe rust resistance genes to 15 Pst races in 66 selected commercial wheat cultivars released from 2000 to 2016. In addition, races CYR32, CYR33, and CYR34 were used to evaluate resistance to Pst at the adult-plant stage of wheat in the field. Four Yr genes (Yr9, Yr10, Yr26, and Yr32) were postulated in 24 wheat cultivars either singly or in combination. Thirty-six cultivars might contain unknown Yr genes, whereas no identified Yr gene was postulated in six cultivars. Yr9 was detected at a frequency of 28.8%, and no cultivars carried Yr5, Yr15, or Yr18. Ten cultivars (15.2%) exhibited adult-plant resistance in the field tests with three predominant races. Three cultivars (Langyan 43, Xinong 889, and Yunfeng 139) had all-stage resistance. These results are useful to growers selecting cultivars and to breeders aiming to use more resistance genes to develop new cultivars with effective resistance in order to reduce stripe rust damage
