Abstract:

In the rice-rapeseed rotation area of northern Jiangxi region，the harvest of rice is constantly delayed due to the pursuit of high yield and high quality，which leads to the inability of rapeseed sowing in proper season. In order to screen rapeseed varieties suitable for late sowing in the rice-rapeseed rotation area of northern Jiangxi region，meet production demand，and accelerate the promotion of excellent rapeseed varieties with late sowing resistance，the experiment was carried out on 23 winter rapeseed varieties collected in the typical rice-rapeseed rotation area in November 2023. The results showed that Jinyouza 9，Qingza 9，Ganyouza 10 and Xunyou 10 yielded more than 110 kg per 667 m²，had strong resistance to late sowing and stress，and were suitable for spreading planting in northern Jiangxi region.

Key words: northern Jiangxi region, late sowing, rapeseed, variety screening
