A spontaneous mutant in cotton ( Gossypium hirsutum L.) is described, and the results of its genetic analysis are reported. This mutant was called virescent‐splash‐leaf because it showed a typical virescent expression, and portions of the leaf surface had a splash‐leaf appearance resulting from abnormal palisade cell development. Expression of the virescent phenotype was consistent, but the splash‐leaf expression was variable. The incidence of the splash‐leaf expression was associated with cool temperatures. The mutant was conditioned by recessive alleles at a single locus. Because it was non‐allelic with any known virescent mutants, it was designated as virescent‐8 and assigned the gene symbols v 8 v 8 . Linkage analysis of virescent‐8 did not reveal any significant association with the marker loci: cup leaf, glandless‐1, frego bract, cluster‐1, virescent‐1, Okra leaf, Red plant, Pilose, Petal spot, Yellow petals, Pollen color, Brown lint‐1, Naked seed, or Green lint.
