运用Eberhat -Rusell模式和方法分析了 1993～ 1994年安徽省中粳区域试验中的 9个品种的稳定性。 80优 12 1两稳定性参数 :( 1)回归系数 (bi)为 0 90 5 8;( 2 )离回归方差 (Sdi2 )为 -5 .0 3 16,比参照种 83 -D两稳定性参数值均小 ,因此认为 80优 12 1是一个稳定性好的杂交中粳组合。在分析 80优 12 1丰产性基础上 ,对其高产途径进行了探讨 ,综合近年来的试验结果 ,总结出 80优12 1高产栽培技术体系 The stability of 9 cultivars in mid-japonica regional trials in Anhui Province from 1993 to 1994 was analyzed by Eberhat-Rusell model and method. 80 12 1 two stability parameters: (1) the regression coefficient (bi) is 0 90 5 8; (2) the regression regression variance (Sdi2) is -5 .0 3 16, than the reference species 83-D two stability parameters Therefore, it is considered that 80% of 12 1 is a stable hybrid rice combination. Based on the analysis of the high yield of 80% 121, the high yielding ways were discussed. Based on the test results in recent years, the high yielding cultivation techniques
