Fusarium oxysporum Schlecht. f.sp. melongenae (FOM), Verticillium dahliae (Ve) and Ralstonia solanacearum
are major limiting pathogens affecting eggplant cultivation and their yield in the world. Natural resistance genes are
the most environmentally friendly method to control the disease. Thus, marker-assisted selection (MAS) is preferred as
a tool for screening resistance genes (R-genes) in eggplant resistance breeding. In this study, markers that are specifically
linked to major disease resistance genes conferring resistance to F. melongenae, V. dahliae and R. solanacearum were
tested in a population containing breeding materials to validate the resistance. Resistant Solanum melongena accessions
LS1934 and LS2436 and their reciprocal crosses were used as the resistance resource for this validation study. Moreover,
classical resistance tests to FOM and Ve were performed with the root-dip inoculation method for classification
of all the accessions based on their resistance/susceptibility responses. The SCAR426, CAPs_903 and SIVR844 markers
were highly informative for the determination of resistance genes (Fomg, Ve and ERs1). Therefore, in areas with high
susceptibility to diseases, a highly efficient combination of the relevant R-genes and their pyramiding into commercial
eggplant varieties are proposed to be implemented as a pragmatic approach.
