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)。
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.
