Abstract:

A segregating cucumber BC1 population was developed using the nearly isogenic lines WI1983G (gynoecious, FFMM) as donor and WI1983H (hermaphroditic, FFMM) as recurrent parent. With screening of polymorphism of one SCAR and, 2112 SSR markers, three polymorphic co-dominant markers SSR23487, SCAR123 and SSR19914 were found to be tightly linking to the M/m gene,with a distance of 0.28 cM, 0.94 cM and 3.20 cM respectively. The interval between SSR23487 and SCAR123, which locate on each side of the M/m gene, was 1.22 cM. These markers not only be useful in markers-assisted selection for gynoecious plant, but also provide a solid basis for isolation of the sex-determining M/m gene in cucumber.
