【摘要】 用高稳系数(HSC)分析法,对贵州省1998～2000年油菜区域试验参试品种进行了丰产稳产性分析。结果表明,HSC值与平均产量(X)呈极显著相关,与变异系数(C.V)值呈显著相关;在1998～2000年两轮交替的13个油菜品种中,黔油14号的HSC值分别为:73.06％、115.87％,均居首位。甘蓝型“三高两低”杂交优质油菜新品种黔油14号具有很好的丰产稳产性。更多还原

【Abstract】 The high and stable yield characters of the rape varieties were analysed by means of the High Stability Coefficient Method (HSC) in the regional trials of Guizhou Province in 1998-2000. The result showed that the value of HSC was most significantly correlated to the average yield (X). and was significantly correlated to the coefficient of variance (C. V). The values of HSC about Qianyou14 were 73.06% and 115.87% respectively heading the list among the alternant 13 varieties in two rounds of the regional trials in 1998-2000. The new variety Qianyou 14 of "Three-high and Double-low" in B. napus was very good.更多还原
