用HSC法与稳定性参数分析杂交油菜的丰产稳产性

Analysis of yield stability of hybrid rapeseed with HSC procedures and stability parameters

采用高稳系数法,辅以稳定性系数和适应性参数,对参加1999～2001年全国冬油菜新品种区域试验(长江上游组)的杂交油菜新品种进行综合分析和评价,结果表明:绵杂95 13(绵油11)为高产稳产性品种;绵杂95 97(绵油12)和95166为高产、不太稳定的新品种;黔油12为低产、不稳定品种。同时,采用区试中常用的品种主效应值法和EberhartRussell法对其丰产、稳产性进行分析,结果完全一致;但HSC法更能客观地反映杂交油菜品种高产、稳产性,计算更为简便。

The High Stability Coefficient(HSC) procedure combined with stability and adaptability parameters was used to evaluate results of winter rapeseed national trials in 1999-2001.The results indicated that the yield of Mianza 9513(Mianyou 11) was high and stable,the yield of Mianza 9597(Mianyou 12) and 95166 were high and unstable,and the yield of Qianyou 12 was low and unstable.The results from HSC procedure were the same as that of other methods usually used in national trials,such as Eberhart Russells method,but HSC procedure was more reliable and more simple.
