Abstract:Stripe rust has been one of the most important airborn diseases threatening wheat production security in China for a long history.Due to the high variability of virulence structures among populations of the pathogen Puccinia striiformis f.sp.tritici(Pst),the disease control of wheat stripe rust in China has been severely challenging.It is the most economical and effective control strategy against stripe rust to develop and widely use disease resistance wheat varieties.As a result,it is valuable to provide new resistance genes and theoretical instructions for disease resistance breeding through identification of resistant germplasm resources and genetic model characterization of the durable resistance varieties.The genetic characteristics of several durable resistant wheat varieties and new lines in China are unknown.In this study,these resistant varieties or lines were used as male parents to cross highly susceptible female parents of‘Taichung 29’or‘Mingxian 169’to set up genetic populations.The offspring plants of the crosses were inoculated with the predominant race of Pst CYR32 at the adult-plant stage for phenotype rating,and their resistant components and genetic traits were analyzed.The resistence of most of the ten durable varieties(eight varieties)against stripe rust was dominated by one or two gene(s)inherited recessively,while most of the six lines(four lines)developed recently contained only one resistance gene,and their propensity of genetic dominance of recessiveness was not significant.Consequently,the resistance gene(s)inherited recessively might play more important roles in the durable resistance varieties.In addition,the new line‘WJ10-97’showed slow rusting to Pst race CYR32 and could be used in wheat breeding programs as a resistant parent.
Keywords:wheat strip rust   persistent resistance   resistance identification   genetic analysis
