Stability analysis for yield and its component traits in sesame (<i>Sesamum indicum</i> L.) genotypes

The current study was performed with 22 sesame genotypes including three checks to identify stable genotypes for different yield and yield attributing traits across three locations (BAC, Sabour; BPSAC, Purnea and ARI, Patna) during two years 2024 and 2025 using Eberhart and Russell model. The stability parameter revealed that the genotypes GT-6, Smarak, Sabour Til-1, BRT-08, BRT-09, BRT-10-1, BRT-12, Suprava and GT-10 had higher seed yield/plant as compared to the population mean. The genotypes GJT-5, GT-6, RT-125, RT-346, AT-384, Sabour Til-1, BRT-08, BRT-09, BRT-10-1 and BRT-12 registered regression coefficient >1. The genotypes GT-4, JLS-120, TLT-07, Smarak, YLM-146, VS-19-045, OSM-79-19-3, Suprava, Kalika, TKG-22, GT-10 and JTS-8 recorded regression coefficient <1. Three genotypes namely BRT-08, BRT-09 and BRT-10-1 recorded non-significant deviation from regression. Thus, in favorable environment genotypes BRT-08, BRT-09 and BRT-10-1 were stable. The genotypes BRT-08, BRT-09 and BRT-10-1, being stable and high yielding genotypes, can be recommended for cultivation under diverse agro-ecological zones.
