Title: METHOD AND APPLICATION FOR STABILIZING HYBRID VIGOR BY UTILIZING VEGETATIVE PROPAGATION CHARACTERISTICS OF ORYZA LONGISTAMINATA
Abstract:
Provided are a method and an application for stabilizing hybrid vigor by utilizing vegetative propagation characteristics of oryza longistaminata. The method comprises the steps: cultivating perennial hybrid rice by utilizing the vegetative propagation characteristics of oryza longistaminata, and stabilizing the hybrid vigor. According to the method and application of the invention, a rice cultivation production manner of continuously harvesting hybrid rice for many years (repeatedly) by planting once due to vegetative propagation is realized, the hybrid vigor of rice cultivation is stabilized, the rice production cost is reduced, and the rice production benefits are improved.
