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

Abstract

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.
