Abstract: Article HistoryExperiments were conducted during the 2022-23 and 2023-24 Rabi seasons at three locations, Line x Tester mating design was used to assess the stability of 67 wheat genotypes for yield and related traits.In Phase I (first stage of the experiment) was carried out to generate fortyfive F1 hybrids by crossing fifteen lines with three testers.In Phase II (second stage of the experiment) was conducted by multilocational trial which involved three locations (one in India and two in Nigeria) using Randomized Complete Block Design (RCBD) with three replications.Standard agronomic practices were followed and data obtained were analyzed using the Eberhart and Russell statistical procedures.The results observed that, there was no stable genotype for all traits.However, some genotypes like DH-3086X PBW-343 and DBW-222X PBW ZN1 revealed high yield with moderate stability for grain yield/plant and other yieldrelated traits.DBW-173 and PBW ZN1 showed the highest stability with moderate yield.For chlorophyll content, the stable genotypes were HD-3721 X PBW-343, PBW-550X PBW-343, and CSW-18.Regarding protein content, DBW-187 and BORLAUG-100 were the most stable and high-performing.Therefore, selection of stable and high-yielding genotypes is reliable and beneficial for genotypes like DBW-173; PBW ZN1 (for grain yield); HD-3721 X PBW-343; PBW-550X PBW-343; CSW-18 (for chlorophyll content); DBW-187 and BORLAUG-100 (for protein content) for wheat improvement across the locations.
