| Abstract: | The objectives of this study were to make known stem rust resistant genes contained in major wheat cultivars grown in four provinces of north China,and resistant cultivars to Ug99.The genes were postulated by the infection type analysis of 52 cultivars pedigree and gene linkages in north China.The 42 single Sr gene lines were combined with 15 pathotypes of Puccinia graminis f.sp.tritici from China and United States.The result showed that 49 cultivars were inferred to contain one or more genes of Sr5,6,8a,9b... |
