采用300Gy60Co-γ射线辐照处理恢7954与蜀恢527的回交后代,经多代选育,育成了优良杂交水稻新组合农丰优2008。2006～2008年参加浙江省衢州市区试和生产试验,2009年通过浙江省农作物品种审定委员会审定。该品种具有杂种优势强、熟期适中、产量高、品质好、抗病性强等特点,增产潜力大。通过审定以来,推广面积不断扩大。该文对其选育研究过程、品种特点及栽培技术等做了系统的总结,旨在为该品种的大面积推广和种植提供一定的技术支持。
Backcrossing progenies of Hui 7954 and Shuhui 527 were treated with 300 Gy 60Co-γ ray radiation. After many generations of breeding, a new hybrid rice combination was developed, which was used by farmers. 2008-2008 Participated in the trial and production of Quzhou City, Zhejiang Province Test, approved by the Zhejiang Provincial Crop Variety Approval Committee in 2009. The variety has the characteristics of strong heterosis, moderate maturity, high yield, good quality and strong disease resistance, and has great potential for increasing yield. Passed the validation, the promotion of an area of continuous expansion. This paper systematically summarizes the breeding process, the characteristics of cultivars, cultivation techniques and so on, aiming to provide some technical support for the large-scale popularization and planting of this variety.
