Abstract:

This study investigated agronomic traits，resistance，and yield indicators of 48 rapeseed varieties under the ecological conditions of Hangzhou region. The results showed that the growth period of the tested varieties ranged from 209 to 222 days，the length of pods was from 6.07 to 11.29 cm，the number of seeds per pod was from 16.64 to 31.56，and the 667 m² yield was from 91.01 to 225.93 kg. Among them，Qinsheng 800，Zhongyouza 19 and Jiayou 5159 performed outstandingly，with yields 32.46%，3.28% and 2.49% higher than the control variety Yueyou 1203， respectively，and they also performed well in terms of growth period and disease resistance. Through multi-dimensional assessment，the above excellent varieties suitable for cultivation in Hangzhou region were screened out，providing a scientific basis for the renewal of local rapeseed varieties，optimization of planting structure and high-quality development of rapeseed industry.
