Abstract
Described are methods of grain production with field conditioned pollen. A method of the present invention includes growing one or more designated female plants that include both female and male components, collecting fresh pollen from designated male plants from a different genetic background, and subjecting the fresh pollen to field conditions, which may regulate pollen moisture content. The field conditioning conditions may include a relative humidity ranging from about 50% to about 100%, a temperature ranging from about −10-10° C., and an air pressure ranging from about 15 kPa to about 150 kPa. These conditions may result in pollen having a moisture content of about 40% to about 58%. The one or more designated female plants are intentionally cross-pollinated with the field conditioned pollen and then grown to maturity such that the grain may be harvested therefrom. Also provided is a method of preventing undesirable pollination in grain production.
