Abstract:Stripe rust and leaf rust are two main diseases threatening wheat production seriously in china.The resistance of wheat varieties in China can be improved effectively by digging and utilizing the germplasm resources of wheat with resistance to these diseases.In this study,57 accessions of Chinese wheat mini-core collections were inoculated to evaluate their resistance to stripe rust and leaf rust at adult stage,respectively.The results showed that,there were 35 cultivars with adult stage resistance to stripe rust and 27 cultivars with adult stage resistance to leaf rust.There were 14 cultivars with adult stage resistance to both stripe rust and leaf rust,accounting for 24.6%of all materials.Among all the resistant cultivars,9 were immune or near immune to stripe rust and 10 were immune or near immune to leaf rust.Furthermore,there were 3 cultivars,Suotiaohongmai,Zhengyin 4 and Zhemai 1,with nearimmune or high resistance to these 2 diseases.This study not only provided valuable resistant resources for wheat breeding,but also provided reference for further studying the Chinese wheat mini-core collections.
