Abstract

Powdery mildew was one of the major diseases in Cucumis sativus L.production.In order to establish its molecular marker-assisted selection system,we aimed to identify molecular markers linked to the resistant gene.With a F2 population between a resistant parent(WIS2757) and susceptible parent(19032),we found two co-dominant SSR markers SSR97-200 and SSR273-300 were linked to the powdery mildew resistant gene,the genetic distances was 5,13 cM respectively.These SSR markers could be useful in marker-assisted selection in cucumber breeding.
