In 1993, Ledhetter started his work to breed a desirable self-pollinating
They both have annual seed cycles with self-pollinating
flowers that rarely cross-pollinate.
Thus, cleistogamous plants should have a low P:O ratio and self-pollinating
plants should have a lower P:O ratio than cross pollinating plants; in this way the P:O ratio is correlated with the reproductive system of the plant (Cruden, 1977).
To generate variation in self-pollinated plants, the plants must be hybridized by manipulating normally self-pollinating
plant flowers to avoid self-fertilization.
Over time, the breeding of tomatoes developed shorter flower styles, when in California in 1965 the fully self-pollinating
plant was developed, featuring a full enclosure of the pistil by the anthers - an assurance of self-pollination.
However, such high levels of polymorphism are not expected for a principally self-pollinating
He and his coworkers dismissed that conclusion by isolating the self-pollinating
Since the plant is an obligate self-pollinating
plant, one can avoid spreading of genetically engineered plants to the environment.
The species is thought to be self-pollinating
throughout its Tasmanian range because some flowers do not fully open.
When an exact duplicate of a plant is desired, especially if it is not self-pollinating
, asexual propagation methods must be used.
When a fruit tree is self-fruitful, it means it is self-pollinating
and that the seeds it produces will grow into trees very much like itself.
If the technology is widely licensed, it could be a boon to the seed industry - especially for companies marketing self-pollinating
seeds such as wheat, rice, cotton, soybeans, oats and sorghum.
