Abstract:

In order to screen semi-wintering wheat varieties suitable for planting in Jiangsu region along Huaihe River, a variety screening test was carried out in Huaihai Farm, Linhai Farm and Xinyang Farm in Jiangsu region along Huaihe River in 2022-2023, selecting 19 semi-wintering wheat varieties validated in recent years with greater potential for popularization, and using Huaimai 33 as the control variety, and carrying out a comprehensive screening and identyficatin of their field growth, yield performance and resistance. The results showed that the average yield level of the control Huaimai 33 was higher and the average yield per 667 m2 was 742.6 kg, and the average yields of Zhengmai 1860 and Yannong 1212 varieties were higher than that of the control Huaimai 33, in which the average yield of Zhengmai 1860 increased by 1.0%, and that of Yannong 1212 increased by 0.3% compared with the control. In addition, Zhengmai 1860 and Yannong 1212 varieties have better performance in the three pilots, and are more widely adapted. In summary, Zhengmai 1860 and Yannong 1212 can be widely planted in Jiangsu region along Huaihe River.
