Cotton plant is a valuable technical crop grown in various regions of the world. For assessing the five colored cotton (Gossypium hirsutum L.) genotypes, the yield contributing traits received 60Co γ-ray irradiation at 0 (control), 100, 150, and 200 Gy. By treating colored cotton cultivars with 100 and 200 Gy rays, variations were visible in early maturity properties. An enhancement in bolls per plant were evident when treating the cream-colored cotton genotypes; however, a decrease occurred in the green-colored cotton genotype. Notably, the colored fiber genotypes treated with 200 Gy ray showed an increased number of bolls per plant. Colored fiber genotypes treated with 200 Gy ray caused a slight fiber elongation than with lower doses of 100 and 150 Gy and the control. The result further revealed cotton genotypes treated with 100 and 200 Gy rays positively affected the yield-contributing traits. The above properties can be beneficial in the selection and improvement of colored fiber cotton genotypes.

Colored fiber cotton (G. hirsutum L.) genotypes treated with 200 Gy had a positive effect on early maturity, bolls per plant, seed cotton yield, and fiber length compared with the 100 and 150 Gy and control.
