The experimental material used in the present study comprised of eight diverse chilli genotypes, which were crossed during Summer season, 2021 to obtain ten cross combinations. The ten cross combinations along with one check DKC-8 were evaluated in RCBD with three replications at three diverse locations during Summer 2022. The analysis of variance was highly significant for all the traits across the three environments. Based on mean performance, hybrids UHF-CHI-5 × UHF-CHI-7, DKC-8 × UHF-CHI-15 and UHF-CHI-13 × UHF-CHI-14 were in the top rank for majority of the traits. Based on Eberhart and Russel model, out of ten hybrids, only two hybrids UHF-CHI-5 × UHF-CHI-7 and DKC-8 × UHF-CHI-7 showed stability for yield and yield attributing traits. Based on GGE Biplot analysis it was observed that E1 (RHR&TS Jachh) was found to be most discriminative and representative. UHF-CHI-5 × UHF-CHI-7 and DKC-8 × UHF-CHI- 7 showed high stability as being placed close to theEnglishThesis
