摘要
[目的]筛选适合赣北棉区种植的双低早熟油菜品种。[方法]通过田间小区试验，对不同油菜品种生物学特性、产量结构、主要农艺性状间的相关指标进行分析。[结果]棉田套播油菜模式下油菜个体较小，株高在160．0 cm以下，茎粗2．0 cm以下，1次有效分枝少于7．0个／株，2次分枝基本没有，单株结角数较少，但套播油菜群体较大。[结论]沣油5103、浔油9号早熟性强且产量高，适宜在赣北棉区种植。
Abstract
Objective] The aim was to screen out double low early maturity rape varieties suitable for cultivated in northern Jiangxi cotton area. [Method] Through plot experiment, biological characteristics, yield, main agronomic traits of different rape varieties were analyzed.[Result] Under the mode of cotton field intercropping with rape, plant height and stem diameter were below 160.0 cm, 2.0 cm respectively, one time ef-fective spouting was less than 7.0 ind./plant and second time spouting was few.Pod number per plant was less, while rape groups were larger. [Conclusion] Fengyou 5103, Xunyou 9 are early-maturing varieties with high yield, which are suitable for cultivated in northern Jiangxi cotton area.
