Plant Breeding, 2001
AbstractThe 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 ...

Facultative Self-pollination in Island Irises
American Midland Naturalist, 1997-Blue flag (Irzs versicolor) is an insect-pollinated clonal plant found in wet habitats throughout northeastern North America. Our study of an isolated population on Kent Island, New Brunswick, showed that blue flag was self-compatible. Moreover, we found no evidence of inbreeding depression.

Insect Induced Self-Pollination
Plant Systematics and Evolution, 1984Significant increase of pod production occurs inLupinus palaestinus Boiss. andL. pilosus Murr. following insect visits. The cause of this increase is investigated through (1) examination of the biology of pollination, (2) examination of pod production under various pollination conditions, (3) examination of cross pollination by genetical markers.

The Makings of Self-Pollination
Science's STKE, 2007Plants that produce both male and female gametes use various strategies to determine whether they will predominantly self-fertilize or predominantly use pollen from other flowers. Although compatibility of cell surface receptors is part of the story, the geometry of flower parts also affects what pollen lands on the stigma.

A self-pollinating mutant of Petunia hybrida
Scientia Horticulturae, 2014Abstract A Petunia hybrida mutant that self-pollinates was identified in an M1 generation of plants mutagenized with ethyl methanesulfonate. A change in floral morphology of the self-pollinating (SP) mutant resulted in flowers with the stigma and anthers in direct contact.

Breeding Self-Pollinated Crops
1987The challenge of the plant breeder is to develop better varieties. In this chapter we are concerned with the methods by which new varieties of self-pollinated crop plants originate. Before we proceed into a discussion of these methods, let us consider the question, “What is a variety?”
