Abstract
This invention describes a new method to generate hybrid seed in any crop plant while also reducing contamination from out-crossings and self-pollination. In contrast to conventional seed production methods, the method of the invention is not dependent on the use of any form of male sterility in the female parent plants, nor the use of isolation distances from unrelated and undesirable plants of the same species, nor the use of male parent plants in proximity to the targeted females. The process involves the delivery of pollen of the male parent at will, as available either in a preserved pollen bank, or using real-time collection from male plants as they become available. Desired pollen is delivered to fertile females during the period when viable pollen from the females and locally proximal unrelated plants is not being released. The delivered male pollen is in such amounts and fortuitously timed that it preferentially pollinates the females and produces relatively pure hybrid seed at levels much higher than if one used current hybrid production practices and did not utilize male sterility practices or prescribed isolation distances. Such fortuitous timing may involve the intenti…
