通过恢复系之间配组育成的早熟粳稻品种京光 6 5 1,在北京区试中增产幅度 (>10 % )和产量潜力接近当前同熟期的杂交粳稻组合 ,2 0 0 0年 4月已通过北京市农作物品种审定。该品种对一般粳稻不育系均具有良好的恢复性 ,可作为恢复系配组应用 ,有可能在早中熟优质高产新组合的选配中发挥重要作用
Through the early maturing japonica rice cultivar Jinguang 6 5 1 with a combination of breeding lines in the restorer line, the yield increase (> 10%) and the yield potential in Beijing district trial are close to the current hybrid rice combination with the same maturity date. In April 2000 Has passed the Beijing crop varieties validation. This variety has good recoverability for general japonica CMS lines and can be used as a combination of restorer lines and may play an important role in the matching of new combinations with good quality and high yield
