为筛选适合在杭埠河灌区推广的抗性好、产量高的优质油菜品种,本研究选择宁R101、陕油28和中油杂501等15个油菜品种开展品种比较试验,对全生育期、主要农艺性状、经济性状和产量等指标进行分析,并对排名前4的品种进行综合评价。结果表明,产量排名前4名的品种分别为中油杂501（3 607.5 kg/hm²）、沣油737（3 378.0 kg/hm²）、大地199（3 279.0 kg/hm²）和豪油杂58（3 229.5 kg/hm²）,这4个品种的农艺性状、综合抗性表现好,产量性状协调,可在研究区以及相似生态区大面积推广。实际种植过程中,沣油737、大地199和中油杂501这3个品种需要重视菌核病的预防及防治。

In order to screen high-quality rapeseed varieties with good resistance and high yield suitable for promotion in the Hangbu River Irrigation area, 15 rapeseed varieties including Ning R101, Shanyou 28, and Zhongyouza 501 were selected for variety comparison experiments, and the whole growth period, main agronomic traits, economic traits, and yield were analyzed as indicators, and the top 4 varieties were comprehensively analyzed. The results showed that the top 4 varieties in terms of yield were Zhongyouza 501 (3 607.5 kg/hm²), Fengyou 737 (3 378.0 kg/hm²), Dadi 199 (3 279.0 kg/hm²), and Haoyouza 58 (3 229.5 kg/hm²). These 4 varieties exhibited good agronomic traits, comprehensive resistance, and coordinated yield traits, making them suitable for large-scale promotion in the researched area and similar ecological areas. In the actual planting process, the three varieties of Fengyou 737, Dadi 199, and Zhongyou River 501 need to pay attention to the prevented and controlled from rot disease.
