Three colored rice varieties were selected and planted in three representative ecological regions(Fumin County, Baoshan City and Weishan County) in Yunnan. The study compared the differences in yield, quality, and anthocyanin content among different colored rice varieties at different ecological sites and explored the correlation between these indicators and meteorological factors during the grain filling and fruiting period. The results showed that the yield, quality, and anthocyanin content of colored rice are influenced by both genetic factors and environmental conditions. Among them, the yield of colored rice planted at the Fumin site was significantly higher than that at Baoshan and Weishan sites, and the rice processing quality was better; the anthocyanin content of colored rice planted at the Weishan site was significantly higher than that at Fumin and Baoshan sites. Correlation analysis results showed that there was a significant positive correlation between daily average high temperature and daily average temperature difference during the filling and maturation stage and yield, and an insignificant positive correlation with anthocyanin content; the daily average high temperature during the grain-filling stage was significantly positively correlated with brown rice width and significantly negatively correlated with brown rice length and length-width ratio. This study provides an important theoretical basis for the promotion of colored rice in Yunnan.
