Progress in selection for fungal-resistant lines can be speeded up by the use of molecular markers associated with genes of resistance. Eight microsatellite regions were used to amplify the DNA of tomato lines (3 resistant 2 susceptible and 3 tolerant). Among loci initially analyzed, SSR-67 was highly polymorphic in the resistant, tolerant and susceptible population. The markerselected is inherited and segregated in Mendelian fashion as demonstrated on a panel of 25F_2 and 20F_1 offspring derived from a cross of two divergent cultivars GP-10 (wilt resistant) and GT-2 (wilt tolerant). 收起
