A case of pleiotropy in sunflower was detected \ilhile studying the inheritance and inter-relations of genes governing anthocyanin pigmentation of the petiole, nidrib, leaf margin, leaf tiP, ray floret, and stigma in a cross between the inbred lines RM-l and lTp-1. Pigmentation was dominant in the F1 generation. Complementary gene action of 9 purple: Z green wâs observed for petiole, midrib, leaf margin, leaf tip, and ray floret colourations in the F2 generation. Colour of the stigma was found to be contrôled byiour pairs of factors which segregated into 207 coloured: 49 coulouress in the Fz. The gene symbols were designated for the above-mentioned characters. The genetic ratios obtaineà in thê Fz generation are verified with the data collected from the F: generation. The occurrence of pleiotropism in sunflowers is reported here for the first time.
