Comparative Study on Production Traits of Main Cultivated Varieties of Double-low Rapeseed in Hubei Province
Abstract：This paper analyzes the production traits of 26 double-low rapeseed varieties that have been registered and promoted in Hubei Province in recent years. The results show that the varieties Yangguang 50, Jinyouza 9, and Zhongyouza 41 have good early maturity and disease resistance, and are suitable for promotion in combination with early rice and regenerative rice. Varieties such as Huayouza 28, Chuza 777, Huayouza 706, Kengyouza 30, Shengguang 165R, Zhongyouza 39, and Dadi 279 have good yield performance and disease resistance, and are suitable for large-scale promotion in the Hubei region. Varieties such as Shengyuan 2, Huayouza 732, Zhongyouza 113, and Lijuza 185 have high single yields but poor disease resistance, so it is necessary to strengthen the control of sclerotinia stem rot when promoting their cultivation.
