In agricultural experimentation, a large number of genotypes are normally evaluated over a wide range of environments for delineating stable genotypes. In this study, fifteen dwarf field pea genotypes were evaluated at six diverse locations under three Agro-climatic zones viz., Central zone, North West peninsular zone and North east peninsular zone for the purpose of identifying stable genotypes through deploying the additive main effects and multiplicative interaction (AMMI) model. The uniqueness of AMMI biplot is to provide comprehensive solution regarding multi-environment evaluation of genotype. In addition to identification of stable genotypes, this approach facilitates effective selection of test environment and allows optimum resource allocation in future testing programme. In the present study from the AMMI biplot and the ASV AMMI stability value (ASV), it was detected that genotypes 6 (Pant-P-345), 12 (KPF-14-50) and 4 (KPMR-940) were the stable genotypes amid the tested genotypes. These identified genotypes with wide adaptation would be valuable treasure troves for the breeder for utilizing as a parent in field pea breeding programme of India.
