水稻超高产育种研究进展

水稻是最主要的粮食作物,水稻产量的稳定提高对于确保粮食安全具有重要的意义。在耕地面积不断减少的情况下,单产的提高是实现增产的唯一途径,超高产育种是摆在农业育种家面前的首要课题。文中就水稻超高产育种的研究现状、新株型创制、杂种优势利用等水稻超高产育种的理论和方法,综述了部分专家学者的观点,并结合北方超高产育种实践对未来超高产育种研究提出了一些粗浅的看法。

Research Progress in Rice Breeding for Super Hgh Yield

Rice is the most important food crop,stable increase of rice yield is significant for food security.In the case of decreasing of arable land,to increase yield per unit area is the only way to achieve production,super-high yield breeding is the primary topics for agricultural scientists.This paper reviewed rice super-high yield breeding research,illustrated the theory and methods of rice super-high yield breeding such as new plant type creation and heterosis utilization,and specified the research direction of rice super-high yield in the future.
