杂交稻特优524的丰产性稳定性适应性分析

Hybrid Rice Teyou 524 Fertility Character Steady Character and Adaptive Character Analysis

利用 1994和 1995两年广东省杂交稻区域性试验资料以及 1995和 1996两年全国籼型杂交晚稻区域性试验资料 ,通过t检验、变异系数和回归系数分别对特优 5 2 4和对照种 (汕优 6 3、汕优桂 33)的丰产性、稳定性和适应性进行分析和比较 ,结果表明 :特优 5 2 4的丰产性、适应性均明显地优于对照种 ,而稳定性则次于汕优 6 3,但好于汕优桂 33,是一个较为理想的迟熟高产杂交稻新组合。

Using the regional trial data of Guangdong hybrid rice in 1994 and 1995, and regional trial data of national late hybrid indica rice in 1995 and 1996, by t test, variation coefficient and regress coefficient, analysis and compare with the fertility character, steady character and adaptive character of Teyou 524 and ck (Shanyou 63, Shanyougui 33) , the result showed: It was obviously that the fertility character and adaptive character of Teyou 524 was better than ck,but steady character was between Shanyou 63 and Shanyougui 33, it was a quite good lat-mature and high-yield new hybrid rice combination.
