Pyramiding of Stripe Rust-resistant Genes and Development of Resistant Wheat(Triticum aestivum)Cultivars for Stripe Rust
摘要
Abstract
The Longdong region of Gansu Province,adjacent to China's wheat(Triticum aestivum)stripe rust oversummering inoculum reservoir(Longnan Region),serves not only as a high-incidence area for the disease but also as a key transmission corridor to eastern wheat production zones,posing a severe threat to local wheat production security.Pyramiding resistance genes to develop wheat varieties with durable resistance is the most economical and effective green control strategy to control the disease's epidemics in this area.This study crossed the slow-rusting wheat line'Longyuan 932'with the highly stripe rust-resistant cultivar'Lantian 15',and pyramided the resistance genes Yr29,Yr30,and YrZH84 through pedigree breeding combined with molecular marker-assisted selection.Two new winter wheat varieties,'Lantian 133'and'Lantian 134',were developed.These varieties exhibited seedling-stage immunity to the high-toxic race of stripe rust CYR33(but susceptibility to CYR34),and exhibited high resistance to mixed pathogen populations at adult-plant stage,and demonstrated adaptability for cultivation in Gansu Province and Ningxia.The development of new wheat varieties with pyramided disease-resistant genes holds significant importance for sustainable control of wheat stripe rust in Gansu Province,and also provides elite parental lines for breeding durable resistance cultivars in China.关键词
