Self-pollination occurs in which of these crops?
Bajra
Mustard
Jawar
Rice
None of these
Rice is a self-pollinated crop with a perfect flower that contains the pistil (stigmas, styles, and ovary) and stamens (two-celled anthers and filaments). Prior to anthesis, which is the period during which the flower is functional, the designated female parent must have its anthers removed before being pollinated with the selected male parent. The process to remove anthers is called emasculation. Hot water treatment and vacuum suction are the two most common emasculation methods. Pollen grains are more sensitive to high temperatures than is the stigma. When treated with water at 113 degrees Fahrenheit for 5 minutes, the pollen grains lose viability while the stigma remains functional.
