Abstract: The nine agronomic characteristics of 31 transformed BADH gene rice species coerced by 0.5 g/L NaCl , namely , ear sprouting period, plant height, ear length, valid ear number per plant ,ripe ear rate ,actual grain number per ear ,fruit bearing rate ,weight of 1000 grains and grains weight per plant were studied through principal component analysis and cluster analysis .Find out five principal components, whose characteristic root accumulate contribute rate were 86.86%. On the base of this, classified the 31 species into four sorts, when Euclidean distance was 2.0 (D=2.0) .The first sort including 10 species belong to more ear sort, the second and the fourth sort including 16 species had better synthetic economic characteristics, and the three sort including 5 species belong big grain sort.
