The importance of 8 traits of Asian rice cultivars which were used as the classificatory criteria by Chen and Oka was evaluated through 4 statistical methods including grey relational analysis, stepwise discriminant method, single traits analysis and principle component analysis. The results showed that the husk colour at heading stage was the most important and easy to be discriminated trait for Asian rice cv. when they were devided into Hsien and Keng. Its incidence degree, coefficient of comformance, common degree and cummulated loading ranked the first,and those of the hair of grain tip and phenol reaction ranked the second. The importance of husk colour at heading stage still ranked the first, phenol reaction the second and finally the hair of grain tip in classification.When rice cv. were divided into Hsien, partial Hsien, medium, partial Keng and Keng types, cold tolerence and resistance to KClO3 played less role in both classifictory methods.
