摘要
本文用贵州省1988—1990年甘兰型双低油菜新品种区域试验的产量为资料,通过联合变量分析,测定新品种的丰产稳产性,结果有三个双低新品种较对照增产。其中87—216平均单产119.2公斤较对照增产14.18%,具有丰产稳产的优点;C—9平均单产114.1公斤,较对照增产9.29%,具有丰产性好,增产潜力大的优点,但是稳产性较差;87—2平均单产106.2公斤,较对照增产2.3%,具有产量稳定的优点,但丰产性一般。
This Paper Showed that through the combining variable analysis determinated the bumper vielding abilty and stability of new varieties by means of the data of yield of Double-low (low erucic acid and low glucosiolate)Brassica napus in Guizhou regional test in 1988-1990. As a result there were three new Double-low rape varieties which the yielcl was respectively more than that of the control, and among them the new variety 87——216 averaged 119.2 kg prt mu to raise by 14.1Kg per to rise by 9.29%, having a good bwmperand stable yield. C——9 averaged 114.18%, it has an advantaga with bumper yielding ability and great productoin potential, but the stability is poor. 87——2 came to 106.2kg per mu, to increase by 2.3%, having a stable yielding characteristic and common yielding ability.
