Seven irradiation induced virescent cotton ( Gossypium hirsutum L.) mutants were analyzed. Four were duplicates of virescent‐1 and two were duplicates of yellowgreen. One virescent was independent of all known virescents. The new virescent was conditioned by recessive duplicate factors, and it was assigned the gene symbols v 5 v 5 ,v 6 v 6 . Linkage analysis showed that the v 5 locus resides in the A subgenome on chromosome 1, adjacent to the L L locus; and the v 6 locus is on the homeologous D subgenome chromosome 15, adjacent to the L o locus. No recombination was obtained between v 5 and L L or v 6 and L o . The results of this investigation firmly establish the homeology between chromosomes 1 and 15.
