Abstract
M2 cotton seeds of mosaic leaves mutants (MC2 and MC3) plants (Gossypium. hirsutum – Coker-310) were used to obtain M3 plants for study the productivity and technological characters. The MC2 mutant was obtained after exposure of dry seeds to 10 K rad gamma rays from Co60 source ,while MC3 mutant was obtained after 24 hrs treatment with 0.03% colchicine solution .This study was carried out according to randomize complete block design (RCBD) during the summer of 2005. The results showed significant differences among the mutants and control plants in : seed cotton yield/plant, maximum lint length, active lint length, fineness of lint, maturity of lint and lint strength and index while there were on significant differences among the plants in : ginning out-turn and seeds index. MC2 mutant showed superiority on MC3 mutant and control plants especially in : maximum and active lint length, lint strength and index.
