Abstract

Abstract:

In this study, 11 new early indica rice varieties including Zhongzu 101 were used as the object, and regional trials were carried out in Jinhua Area. The results showed that Jiachuang 92 had the highest yield, with a yield of 645.0 kg at 667 m², followed by Yongxian 980, with a yield of 641.7 kg, and the growth period was 3 and 5 days shorter than that of the control, respectively. This study provides a theoretical basis for the trial introduction of Jiachuang 92 and Yongxian 980 varieties in Jinhua Area.

Key words: new variety, early indica rice, regional trials

CLC Number:

S511
