Abstract:

In order to further ensure the high yield and high-quality collaborative production of rice in the southwestern mountainous areas of Zhejiang Province, nine newly approved rice varieties were introduced and planted for this study, with the most widely cultivated high-quality indica rice variety Zhongzheyou 8 as control. The reproductive period, yield, quality, temperature and light characteristics of the 10 tested varieties were comparatively analyzed, and the results showed that all the tested varieties were able to reach maturation in the southwestern mountainous areas of Zhejiang Province, but with significant differences in yield and quality. The comparative standards of this study for rice was set with the 667 m² yield of 450 kg and the edible quality standard of NY/T 593-2021, compared with the comparative standards, Zhongzheyou 8, Huazheyou 210, and Zhongzheyou 518 were selected as qualified for the synergy between high yield and high-quality.

Key words: southwest mountain area of Zhejiang Province, indica rice, yield, quality
