[目的]探索出适应当地自然生态条件、丰产性好、生育期适中的油菜品种。[方法]利用2012年至2015年绵阳杂交油菜新组合区域展示试验资料,对3个组合在四川5个不同生态区的产量及产量构成因素、组合与试点的互作效应等进行了分析。[结果]绵油33、绵油88和绵油309产量差异不显著,都是高产品种。经过方差分析,高芥酸油菜绵油309的产量最高,具有较大的推广潜力,适合高芥酸油菜基地大力推广种植。绵油88、绵油33是双低品种,在丘陵区及其类似地区推广,有较强的高产性和丰产稳定性。[结论]该试验为四川丘陵区域各基地县油菜生产推荐适宜种植的主栽品种提供了参考。
[Objective] The research aimed to explore varieties of rapeseed suitable for the local natural ecological conditions, good yield and moderate growth period. [Method] Based on the experimental data of the new hybrid rapeseed assemblage in Mianyang from 2012 to 2015, the yield and yield components of the three combinations in five different ecotopes in Sichuan Province, the interaction effect between the combination and the pilot plant were analyzed. [Result] The results showed that there was no significant difference in the yield of Mianyang 33, Mianyou 88 and Mianyang 309, all of which were high-yielding varieties. After analysis of variance, the output of high erucic acid rapeseed oil 309 is the highest, which has great potential for promotion and is suitable for planting high erucic rapeseed base vigorously. Mianyou 88, Mianyang 33 are double-breed varieties, which are popularized in hilly areas and similar areas and have strong high yield and high yield stability. [Conclusion] The experiment provided references for the main cultivars suitable for rapeseed production in all counties and counties in Sichuan hilly area.
