摘　　要：用Eberhart和Russell法,对绵油11号在4a中的各种试验资料进行分析表明,杂交油菜绵油11号在不同地区,不同的气候条件下的丰产、稳产性好,适应范围广。通径分析结果表明,影响产量构成的三因素中,单株有效角果数的直接作用最大,千粒重次之,角粒数的影响作用最小,因此在高产栽培上要主攻单株有效角果数,同时兼顾角粒数和千粒重。The data from the different experiments in 4 years were analysed by using Path analysis and Eberhart-Russell's methed for Mianyou No. 11 . The results indicated that hybrid rape Mianyou No. 11 showed the characteristics of high and stable yield ,wide adaptability in different regious and under different climate conditions. Among the yield component factors, the effective ponds per plant had the highest effection on yield,the second was 1000-seeds weight and seeds per pod had the smallest effect on yield . So the strategy in high yield cultural technigues of Mianyou No. 11 would be to raise the pods per plant mainly and at the same time give consideration to both seeds per pod and 1000-seed weight .
