摘　　要：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12The yield stability of nine rice variety from the test trail group of middle japonica rice in Anhui Province in 1993 and 1994 was analyzed with the model and method of Eberhat-rusell. Two parameters of the stability of 80 You 121 was as follow: (1)regression coefficient (bi) was 0.9058 ; (2) differential regression variance(S) was=-5.0315 5. Either of the values was less than that of check variety 83-D, which indicated that 80You 121 was a good stable japonica hybrid rice. Based on the productivity of 80 You 121, its high yield way was discussed. Compared with the results of 80 You121 tested in recent years and the measurement of effective cultural techniques for high yield were summarized.
