Abstract :The economical and effective weed control in cotton can succeed by breeding IMI-tolerant genotypes. For this purpose, we treated seeds with gamma rays at different doses and sprayed the plants with imazamox in M1-M5 generations. Thirty-three M4 lines in 2020 and seventeen M5 lines in 2021 with two comparative varieties were arranged in a Randomized Complete Block Design with three replications. M4 lines generally had superior fiber properties than standard varieties. We transferred 17 M4 lines, superior in terms of yield, ginning out-turn and fiber quality, to the M5 generation. All M5 lines exhibited finer fibers than comparative varieties. Seed cotton yield and ginning out-turn of eight M5 lines were superior to the comparative varieties. Five IMI-tolerant genotypes with high yield and favourable fiber quality were transferred to further generations.
