利用 1996和 1997两年早造广东省区域试验资料以及 1997年全国籼型杂交稻 (中早熟组 )区域试验资料 ,对优优 12 2的丰产性、稳定性和适应性进行了分析和比较。结果表明 :优优 12 2的丰产性、稳定性和适应性都明显地优于对照或相当 ,是一个较为理想的中早熟杂交稻新组合
Based on the regional test data of early Guangdong Province made in 1996 and 1997 and the regional experiment data of National Indica Hybrid Rice (middle and early - maturing group) in 1997, the yield, stability and adaptability of Youyou 12 2 were analyzed and compared. The results showed that the high yield, stability and adaptability of youyou12 2 were significantly better than those of the control or equivalent, which was an ideal new combination of middle-early-maturity hybrid rice
