Stability analysis of chickpea (Cicer arietinum L) genotypes for major quantitative traits

A study was conducted to evaluate the stability and performance of 16 chickpea genotypes across three different sowing environments in Pune, Maharashtra. The research utilized a randomized block design and analyzed five key traits. The results confirmed a significant genotype × environment (G × E) interaction for all traits, indicating that genotypes performed differently depending on the sowing date. The earliest sowing date (20 October) proved to be the most favourable environment, leading to the best overall growth and yield. The analysis successfully identified several genotypes with average stability, meaning they were well-suited for a range of environments. Specifically, Phule Vikram, PG-1609-4-19 and PG-1628-15-13 were found to be stable, high-yielding genotypes. The study also identified genotypes with unpredictable performance and one (PG-211110) with above-average stability, making it ideal for less favourable conditions. These findings provide valuable information for breeders and farmers seeking to select stable, high-yielding chickpea varieties adapted to diverse environments.
