北方粳稻新株型超高产育种研究进展

New Plant Type Breeding for Super-high Yielding Northern Japonica Rice

以沈阳农业大学水稻研究所40多年来的研究成果为主,从籼粳稻杂交、新株型创造及新品种选育等方面综合评述了北方粳稻超高产育种理论与实践研究进展,讨论了水稻超高产有关的生理与遗传基础问题,指出新株型超高产育种是实现水稻单产第三次飞跃的重要途径。

Based on the research achievements for over 40 years obtained by Rice Institute, Shenyang Agricultural University, the authors comprehensively analyzed the theory and practice for super high yield breeding of northern japonica rice in terms of crossing between indica and japonica, creation of new plant type and development of new varieties. Physiological and genetic problems in super high yielding rice were discussed. Breeding of super high yielding new plant type of rice is a key for realizing the third breakthrough at rice yield.
