Abstract

Abstract:

In order to screen out the excellent rice varieties suitable for planting in Yuhang, and grasp the characteristics and production performance of the main varieties of late rice, according to the unified arrangement of Zhejiang Provincial Seed Management Station and Hangzhou Seed Service Station, combined with the actual production of late rice in Yuhang District, a demonstration test was carried out. The results showed that the indica-japonica hybrid rice Yongyou 7872 and the conventional late japonica rice Zhongjia 8 had a shorter growth period and higher yield. In addition, the phenotype of the yield components of Zhehujing 25 was relatively average, the yield was relatively stable, the increase rate was higher, the resistance was good, and the comprehensive performance was good. Yongyou 7872, Zhongjia 8 and Zhehujing 25 are suitable for further promotion and planting in Yuhang District.

Key words: rice, new varieties, demonstrations, variety screening
