Genotype x Environment Interaction and Stability Analysis in Indian Bean (Dolichos lablab (L.))

Abstract

An experiment was conducted at Pulses Research Station, Navsari, Agricultural Research Station, Achhalia, and Regional Rice Research Station, Vyara during the season of 1995–96 to study the G × E interaction and stability performance in Indian bean. The G × E interactions were significant for all the traits except 100-seed weight. Among parents, NVS-141 was found to be stable for seed yield per plant, while NVS-61 and NVS-62 were found stable under unfavourable environments. The highest yielding hybrid, Red Paria × AKW-9304, was found stable for seed yield in unfavourable environment. While the high-yielding hybrids NVS-61 × NVS-102, 125-36 × NVS-121 and Red Paria × NVS-102 were identified as stable for seed yield per plant, specifically under good farming conditions.
