Identification of disease resistance of Xinjiang wheat based on KASP technology
[Objective]This study aims to identify the genes related to disease resistance of Xinjiang wheat varieties(lines)and provide materials for genetic improvement of wheat breeding.[Methods]In the present study,KASP technology was used to detect the genes related to disease resistance in 183 Xinjiang wheat varieties(lines).[Results]The results showed that 99 varieties had the leaf rust resistance gene Lr46 with a frequency of 54.10%,64 varieties had the leaf rust resistance gene Lr14a with a frequency of 34.97%,3 varieties had the leaf rust resistance gene Lr68,no variety had the powdery mildew resistance gene Pm21 and yellow rust resistance gene Yr15.The distribution frequency of resistance genes in Xinjiang wheat varieties(lines)was low with a frequency of about 26.8%.[Conclusion]The 146 selected materials could be used as resistance materials for wheat breeding of long term rust resistance in Xinjiang.
