Evaluation of Resistance to Strip Rust of Wheat Cultivars Released in the Past Decade in Hubei Province

To understand the status of resistance to stripe rust among the wheat cultivars released in the past decade in Hubei,the adult resistance to stripe rust of those cultivars was evaluated and the origins of their resistance were analyzed by pedigree analysis.The results indicated the resistance to stripe rust among these cultivars were lower in general and the origins of resistance were mainly inherited from Fan6,Nanda2419,Afu and Funo.It suggested that the effective resistance resources were narrow and the resistance of them had lost,so the breeding on resistance to stripe rust should be strengthened promptly in Hubei province.
