Study of the traits and characteristics of the variegated cotton mutants Leaves - Third generation (M3)
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...

| Summary: | 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.<br /> 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. |
