摘要: Somaclonal variation could be utilized for genetic improvement of cotton (Gossypium hirsutum L.). Although significant progress has been made in cotton regeneration, the phenotype of regenerated plants has rarely been investigated. We report here the phenotypic variation of regenerated cotton plants. Extensive variations exist in the F-0 generation and subsequent progenies of regenerated plants. Most of the phenotypic variations in F-0-regenerated plants were physiological or epigenetic and were not inherited by offspring. However, we have obtained sterile plants, and elite lines with characters of bigger boll, higher lint percentage or longer fibre from the progenies of regenerated plants. These variations in the F-1 plants were steadily inherited into the F-2 generation. The results will promote the application of plant tissue culture to cotton improvement.
