从向日葵亲本、F1和分离群体中获得了关于红色、黄色、橙子和柠檬射线花颜色、管状射线花、花青素着色的盘花和舌状盘花的遗传数据。在与黄花系杂交的一个组合中，红花颜色明显受2对互补上位作用的基因控制。与橙子和柠檬系杂交的花色呈单基因遗传。黄、橙子、柠檬3个品系间的杂交结果表明，黄对橙子为显性，柠檬对黄、橙子为隐性上位，两对基因能充分解释这一结果。在黄色的十字架上。两个基因互作产生的F2分离比为9黄：3橙子：4柠檬。在F2中1个基因的分离在黄色×黄色中观察到。橙子和橙子×柠檬十字架管状射线花和花色苷花盘花分别受一对隐性和一对显性基因控制。舌状花在正常花型中占优势，F2分离比表明至少有2个基因参与。
Genetic data on the inheritance of red, yellow, orange, and lemon ray flower color, tubular ray flowers, anthocyanin-pigmented disc flowers, and ligulate disc flowers were obtained from parental, F1, and segregating populations of sunflowers. Red flower color was apparently controlled by 2 genes with complementary epistatic action in one cross with a yellow-flowered line. Monogenic inheritance was suggested for red flower color in crosses with orange and lemon lines. Crosses among yellow, orange and lemon lines indicated that yellow was dominant to orange, lemon showed recessive epistasis to yellow and orange, and that 2 genes adequately explained the result. In crosses of yellow .times. lemon the interaction of these 2 genes produced F2 segregation ratios of 9 yellow:3 orange:4 lemon. Segregation in F2 for 1 gene was observed in the yellow .times. orange and orange .times. lemon crosses. Tubular ray flowers and anthocyanin-pigmented disc flowers were controlled by a single recessive and single dominant gene, respectively. Ligulate disc flowers were dominant over normal flowered types and the F2 segregation ratio suggested that a minimum of 2 genes was involved.
