In this paper 7 Japanic rice varieties (Oryza sativa L.) were planted in 6 different altitude locations in Yunnan Province to study the influence of elevations on rice grain quality, and the ANOVA，Cluster and PCA analysis methods were conducted to evaluate the genetic by environment interaction on rice quality ponents. The results showed that Gel consistency and chalkness rate were greatly influenced by altitudes。 head milled rice rate was less. While Brown rice rate and milled rice rate as well as grain length were not affected by altitudes, indicated these quality ponents were controlled by genetics and without GE interaction. Amylose content had less variance among altitudes, but there were significant difference among varieties, means the genotype was the main factor. The results suggest that Under plateau climate, Japanic varieties should be displayed according to their own adaptive area to gain high yield and quality.Key words: Japonica rice。 altitude。 rice quality
