New Virescent Cotton Mutant Linked with the Marker Gene Yellow Petals¹

A new virescent mutant in cotton (Gossypium hirsutum L.), which occurred spontaneously, was found in the Cotton Breeding Nursery at the Texas Agric. Exp. Stn., College Station, Texas. Inheritance tests indicate that the phenotypic expression of this mutant is controlled by a recessive gene at a single locus that, when homozygous, results in virescent foliage. The degree of yellowness expressed by this mutant during its period of maximum expression is comparable to the expression of virescent-1 (v₁) or yellow green (yg₁yg₂) at College Station. Linkage tests indicate that this new virescent mutant is linked about five crossover units from Yellow petals (Y₁), comprising a new linkage group in cotton, and it is independent from 16 other marker mutants tested. It is proposed that this new virescent mutant be named virescent-10 and assigned gene symbol v₁₀, and the new linkage group be designated Linkage Group XII.
