利用1996和1997两年广东省区域试验资料以及1997年和1998两年华南早籼组区域试验资料,通过t检验、变异系数和回归系数分别对优优128和对照种(汕优63、汕优桂99)的丰产性、稳定性和适应性进行分析和比较。结果表明:优优128的丰产性、稳定性和适应性都明显地优于对照种或相当,是一个较为理想的迟熟杂交稻新组合。
Based on the regional trial data of Guangdong Province in 1996 and 1997 and the regional test data of early indica rice in South China in 1997 and 1998, the t test, coefficient of variation (CV) and regression coefficient were used to analyze the genetic diversity of Youyou 128 and Shanyou 63 99) were analyzed and compared for their high yield, stability and adaptability. The results showed that the excellent yield, stability and adaptability of Yyou 128 were significantly better than those of the control or equivalent, which was an ideal new combination of late maturity hybrid rice.
