- Abstract
【Objective】 To clarify the distribution of stripe rust resistant genes Yr 9, Yr 26 and Yr Tp1 in 153 winter wheat varieties from Xinjiang with a view to providing theoretical basis for resistance breeding of Xinjiang winter wheat. 【Methods】 The SSR marker of stripe rust resistant genes, polymerase chain reaction and polyacrylamide Gel electrophoresis were used to detect whether the tested wheat varieties contain Yr 9, Yr 26 and Yr Tp1 genes. 【Results】 The percentage of 123 winter wheat landraces and 30 cultivars from Xinjiang that carried Yr 9 was 78.86% and 63.33%, respectively; Yr 26 was 95.12% and 73.33%, respectively; Yr Tp1 was 88.62% and 60%, respectively; In 123 winter wheat landraces, we identified that all the three resistant genes in 87 varieties (70.73%), two resistant genes—the gene recombination types including Yr 9+Yr 26, Yr 9+Yr Tp1, Yr 26+Yr Tp1- in 28 varieties (22.76%), only Yr 9 in 1 variety, only Yr 26 in 5 varieties; In 30 winter wheat cultivars, we detected all the three resistant genes in 15 varieties (50%), two resistant genes—the gene recombination types including Yr 9+Yr 26andYr 26+Yr Tp1 in 7 varieties (23.33%).【Conclusion】 Above all, it is concluded that the winter wheat germplasm in Xinjiang carrying the Yr genes are abundant and these germplasms can be used as intermediate materials in disease resistant breeding.
