Abstract:

This article provided a brief analysis of glutinous rice varieties in the regional trials of new rice varieties in Zhejiang Province from 2019 to 2023. The results showed that a total of 27 glutinous rice varieties were tested 38 times in Zhejiang Province over a period of 5 years. As of 2023,only 4 of the new rice variety regional trials had completed the approval process in Zhejiang Province. Most of the tested varieties had a single dominant trait such as high yield,disease resistance,high quality or a combination of two dominant traits,and almost none had comprehensive dominant traits such as high yield,high quality,and disease resistance. In the future,the breeding objectives of new glutinous rice varieties in Zhejiang Province should shift from focusing on single indicator such as high yield,high quality,and disease resistance to emphasizing comprehensive trait indicators such as high yield,high quality,and disease resistance. This study provided a reference value for the breeding and improvement of glutinous rice varieties.
