Evaluation of Stripe Rust Resistance in International Wheat Germplasms
摘要
Abstract
Stripe rust is an important disease that threatens the safety of wheat production.Breeding and planting resistant varieties are the environmental-friendly and economic ways to control the disease.In order to find the new resistance resources for wheat breeding against stripe rust,a total of 376 international wheat germplasms were identified for stripe rustresistance from 2013 to 2023.The results showed that 88 wheat varieties were resistant to stripe rust,accounting for 23.40%of the wheat varieties.26 varieties were high to immune resistant to the disease,62 varieties were moderate resistant,and 192 varieties were slow rusting to the disease.The varieties carrying resistance genes Yr3、Yr5、Yr15 and YrZH22 were near-immune to immune for stripe rust,while the varieties carrying multiple or single resistance genes(eg.,Yr1,Yr2,Yr3a,Yr4a,Yr3b,Yr4b,YrDa1,YrDa2,Yr16,Yr13,Yr25,Yrsp,YrH46)were moderate resistant to stripe rust.The immune or high resistance varieties can be used as parents in future wheat breeding,while those varieties containing unknown resistance genes,as well as varieties with slow rusting,need to be further explored in wheat breeding based on their agronomics traits and resistance background.关键词
