Abstract:

To screen superior winter rapeseed varieties suitable for Hangzhou，this experiment conducted systematic observations on 33 winter rapeseed varieties at the Hangzhou Original Seed Farm，focusing on growth period，stress resistance，yield，and other traits. A comprehensive evaluation was performed in combination with climatic conditions during the planting period. The results showed that varieties such as Ningza 182，Zhongyouza 501，and Tengyou G50 performed outstandingly，with moderate growth period，strong lodging resistance，high yield，and excellent disease resistance，making them suitable for promotion as superior varieties. Varieties such as Shengguang 2003，Zhongyouza 41，and Qinyou 908 also demonstrated good potential and can be considered as promising candidates for further attention. This study provides a scientific basis for the rational selection and promotion of local winter rapeseed varieties in Hangzhou.
