Comparative experiment on resistance and yield of high-quality rapeseed varieties in Hangbu River Irrigation area
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 (3607.5 kg/hm2),Fengyou 737 (3378.0 kg/hm2),Dadi 199 (3279.0 kg/hm2),and Haoyouza 58 (3229.5 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.
