Immature Fiber Mutant of Upland Cotton

Abstract

The inheritance of a mutant character of Upland cotton, Gossypium hirsutum L., that results in abnormal fiber development is described, and the mutant is compared to environmentally induced immature fiber. The phenotype and fiber properties of the mutant resemble those found in bolls that have experienced arrested development due to environmental conditions. Seed of the mutant plants however, showed normal development. The mutant expression was conditioned by homozygous recessive alleles at a single locus and assigned the gene symbol im.
