Cleome hasslerana Chod., a cross-pollinated species, has 5 corolla colors: violet, lilac, red, pink, and white. F1 and F2 progenies produced from crosses among the cultivars Helen Campbell Snow Crown, Cherry Queen, Pink Queen, and Violet Queen indicate that 3 loci with 2 alleles per locus control flower color. The allele W, for colored corolla, is dominant to w, for white corolla; R, for violet color, is dominant to r for red; and I, for dilute flower color, is dominant to i, determining intense flower color.
