Abstract
ABSTRACT
The present investigation titled, “Genotype × Environment interaction in some chilli
cross combinations” was carried out at three diverse locations viz., RHR&TS Jachh (E1),
UHF, Nauni (E2), RHR&TS Bajaura (E3) during Summer of 2021 and 2022 to study the
mean performance, and stability analysis according to Eberhart and Russel model for yield
and yield attributing traits in chilli. 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 the
