Background: Extreme phenotypes carried on by transgressive segregation are, moreover, heritably stable in contrast to heterosis. It has been hypothesized that the development of extreme or “transgressive” traits segregating hybrid populations assists adaptive divergence taxa. The investigation French bean was experimented evaluate segregants generated F2 generation for yield and related traits. Methods: present study conducted during rabi 2019 2022 elicit data produced generation. Fertile F1 hybrids were developed from three crosses: IC 632961 × Arka Sukomal, Arjun 63296. Heterosis estimated these hybrids. progeny evaluated open field condition. Mean, standard deviation percentage quantitative under investigation. Result: Transgressive observed all crosses, with highest number found cross Sukomal. identification isolation such indicate parents possess favourable alleles genes governing interest, which can be consolidated into a single few genotypes through stringent selection. Superior desirable sixteen its component traits, except leaf length, two combinations Arjun. inflorescences per plant (79.49%), followed pods (78.46%) pod (75.61%)
