基　　金：support by the Ministry of Science and Technology,China (2011CB100403);the Ministry of Agriculture,China (200903035);the Special Project from State Key Laboratory for Biology of Plant Diseases and Insect Pests,Chinese Academy of Agricltural Sciences (SKL2009OP09) 摘　　要：The objective of this study was to characterize yellow(stripe) rust resistance gene(s) in 52 commercial wheat cultivars from Yunnan Province in China,and to provide information for their rational deployment in field.Seedlings of wheat cultivars were inoculated with 25 differential isolates of Puccinia striiformis from foreign and home to postulate resistance genes to yellow rust,and then validated by pedigree.There were 10 probable resistance genes characterized in these cultivars,in which,Yr9 was most commonly postulated to be present in thirteen cultivars.Yr21,the second,was present in four cultivars.Yr8,the third,were present in three cultivars.Yr6,Yr17 and Yr26,the fourth,was present in two cultivars respectively.The other gene(s) such as,Yr2+YrA,Yr7 and Yr27,were only present in single cultivar(s);unknown gene(s) or gene(s) combination(s) were present in 22 cultivars.One cultivar(Yunmai 42) had no resistance gene tested in this study.Cultivars such as Yunmai 52,Mian 1971-98,Kunmai 4,and Yunmai 56 carried effective genes and can be popularized mainly;Yr9 should be planted with other Yr genes.In the meantime other effective genes should be introduced to realize gene diversity for controlling wheat yellow rust.Yunmai 42 should be reduced to avoid rust breakout.Unknown gene cultivars should be utilized and be researched deeply. 关键词：小麦品种小麦条锈病抗性基因云南省幼苗中国商业云麦42
