SSR Markers Linked to the Resistant Gene of Cucumber Powdery Mildew

doi:10.7668/hbnxb.2008.06.017

Abstract

Abstract: Powdery mildew was one of the major diseases inCucumis 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 F-population between a resistant parent(WIS2757)and susceptible parent(19032),we found two codominant 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.

Key words: ucumis sativuL., Powdery mildew, SSR
