Notes:
The mechanism and inheritance of intraflower self-pollination in self-pollinating variant strains of periwinkle was studied using three self-pollinating and two non-self-pollinating but fully self-fertile strains. Intraflower self-pollination in self-pollinating strains occurred due to the continued growth of the gynoecium beyond the base of the anthers, even after anthesis, resulting in intraflower self-pollination. In non-self-pollinating strains, the stigma remained below the base of the anthers and did not come into contact with the pollen up to flower drop. Intraflower self-pollination was found to be governed by duplicate recessive genes. The utility of the intraflower self-pollination trait in the breeding of periwinkle cultivars is discussed.
