摘要
研究了长江下游地区优质油菜新品种的丰产性和稳产性，并对其高产稳产机制进行了探讨。结果表明，产量构成三因素对产量的贡献大小顺序为，单株有效角果数＞每角粒数＞千粒重。产量的稳定性取决于产量构成因素的稳定性及相互作用。其中产量的稳定性与单株有效角果数的稳定性相关最密切，其次是千粒重的稳定性，每角粒数的稳定性对产量的稳定性影响最小。高产稳产品种一般单株有效角果数较多，且单株有效角果数和千粒重的稳定性较好。
The meachanism of high and stable yield of quality rapeseed in lower Yangtze region was studied.The results were as follows: The sequence of the three factors contribution to the seed yield was effective pods perplant,seeds per pod 1000-seed wight.Stablity of seed yield depended on the stablity of the three yield factors ,there was closer relation between the stability of effective pods per plant and seed yield ,stability of 1000-seeds wight and seeds per plant were of comparatively less importance.
