Description The present study was taken up to diversify the pistillate and monoecious lines to be used in hybridization programme. Mutagenesis was carried out using the chemical mutagen ethyl methane sulfonate (EMS) to induce mutation in popular pistillate line DPC 9 and land race Rasipuram local. The segregating mutant population was evaluated for their wilt resistance by screening in wilt sick plot. Plant to progeny row was continued up to M5 generation by selecting superior progenies in terms of yield and wilt resistance. Skewness and kurtosis indicated the presence of gene interactions for most of the traits studied. The pistillate progeny M5 29-11-5 (YRCP 2) and the monoecious progeny M4 106-2-3(YRCS 1904) were found to be the promising one and this could be further utilized as parents in hybrid development process.
