Current Status and Strategies for Utilization of Stripe Rust Resistance Genes in Wheat Breeding Program of China
Wheat stripe rust caused by Puccinia striiformis f.sp.tritici(Pst)is a devastating disease threaten food security in China and worldwide.Epidemics of wheat stripe rust have been under control through applying resistant cultivars and crop protection approaches.However,due to climate change,innovation of cropping system,improvement of breeding technology,yield level enhancement of wheat cultivars,variation in structure and frequency of virulence genes in Pst populations in the new era,the current status of stripe rust resistance genes in wheat breeding programs need to be evaluated.The results could provide useful information for applying stripe rust resistance genes to develop new wheat cultivars with broad-spectrum and durable rust resistance.After multiple year's stripe rust resistance survey,genetic analysis,molecular tagging and mining of stripe rust resistance genes in wheat cultivars and advanced breeding lines,the current status of major stripe rust resistance genes utilization was reviewed.We summarized the present situations of major stripe rust resistance gene discovery and germplasm innovation,the most frequently used stripe rust resistance genes,new strategy for pyramiding adult plant partial resistance and all stage resistance,and molecular marker assisted selection for developing wheat cultivars with broad spectrum and durable resistance in China.This review also proposes the major research areas in wheat stripe rust resistance breeding in the new era.
