Abstract:

A field comparison experiment involving 30 rapeseed varieties was conducted at the Hangzhou Raw Seed Growing Farm from 2024 to 2025. Through systematic observation and comprehensive evaluation of indicators such as phenological period,agronomic traits,yield components,and stress resistance,varieties with high yield and strong stress resistance suitable for the ecological conditions of the Hangzhou region were screened out. The results showed that the growth period of the tested varieties ranged from 221 to 240 days,with most maturing in mid-May,which facilitates crop rotation. Significant differences were observed in economic traits;among them,the variety Zheyouza 808 achieved the highest yield of 247.24 kg per 667 m2,while varieties Yueyou 1203 and Yueyou 1510 also demonstrated excellent performance. All varieties exhibited good cold tolerance,with low incidences of sclerotinia rot,viral disease,and clubroot. Zhenongyou 8 and Zheyouza 59 showed superior lodging resistance. In summary,varieties such as Zheyouza 808,Yueyou 1203,and Yueyou 1510 performed outstandingly in terms of yield,stress resistance,and adaptability,making them suitable for promotion in Hangzhou and similar ecological regions. The findings of this study provide a scientific basis for rapeseed variety selection and high-yield,high-efficiency cultivation practices in the Hangzhou area.
