| 摘 要： | 为提高耕地单产,适应耕地面积逐年减少的现状,利用同质恢渗粳的部分亚种间杂种优势的杂交模式,聚合了强优势、耐冷等多个优异性状,通过异地穿梭育种,定向选择育成了杂交水稻三系恢复系G569,利用G569与不育系五丰A配组育成的五丰优569丰产性好,耐冷性强,稻瘟病抗性较好,食味佳,株型适中,生长势强,于2011年通过湖南省审定(湘审稻2011034号).

| Abstract: | To enhance the per capita yield of rice,so as to adapt to yearly decreasing of arable land,On the basis of inter-subspecific heterosis,many excellent properties,such as strong superiority and cold tolerance,were polymerized.Through the method of shuttling breeding off sites and directional selection,a new restorer line G569 was developed.Wufengyou 569,which was developed with G569(restorer line) and WufengA(sterile line).This three-line hybrid rice cultivar was approved by Hunan Province in 2011 because of its better performance,including high-yielding,strong cold tolerance,blast resistance and taste values. |
