Abstract:
The present investigation was designed in order to estimate the G×E interaction and stability parameters for fruit yield and its components over environments in eggplant. The experimental material comprised of 8 parents, their resultant 28 hybrids produced following half diallel mating design and a standard hybrid check “GJBH-4” of eggplant, which were evaluated in randomized block design with three replications. The experiment was conducted at three different locations of Navsari Agricultural University, Navsari during rabi 2020-21. Stability analysis results indicated that both linear and non-linear component played an important function in building up G × E interaction in our experiment. The stability ANOVA deciphered that genotypes (parents, hybrids and check) mean squares had displayed highly significant trend for all of the characters while G × E was highly significant only for branches per plant when tested against pooled error. The environmental index study revealed that Waghai (L3) has the most auspicious location and had well-nourished majority of the characters. The stability parameters analysis for branches per plant character confirmed that BPG-3 displayed above average response and specifically adapted to unfavorable locations in comparison to all the other parents. GJBH-4 (check) displayed average response along with high stability under all locations for branches per plant.
