The investigation on diallel analysis in french bean was carried out for thirteen yield and yield attributing characters. The material comprised of six parents and 15 F1 hybrids without reciprocal designed in RCBD with two replications. The parent, ArkaKomal is the best combiner for many characters and hybrids ArkaKomal x ArkaSuvidha, Arkakomal x Black seeded, Gokak local x Arabhavi Local, Gokak Local x Ring bean were shown high perse performance. The additive (D) genetic variance was significant for Days to first flowering, Days to fifty per cent flowering, Days to maturity and pod length. The sum of dominance effect over all loci (h2) was significant for number of branches at 60 DAS, Days to first flowering, days to fifty per cent flowering, pod weight, number of seeds per plant and hundred seed weight. Dominant components (H1 and H2) were showed significantly difference for plant height at 30 DAS and 60DAS, number of branches at 30 and 60DAS, days to first flowering, days to fifty per cent flowering, days to maturity, pod length, pod weight, number of seeds per plant and hundred seed weight. Magnitude of dominance effect is more compare to the additive component, hence solution may be practiced in the segregating population and also inter mating of the selected plants in segregating population or recurrent selections may be practiced to improve the yield.
