Total of 34 accessions of weedy rice from difference countries were analyzed with data from 8 agronomic traits. With those data, four principle elements were obtained, which contributed variance over 88.071%. Based on the principle elements, the weedy rice were clustered into 4 groups. One had early heading date with short stem and small panicles with less grain number. The second had high stem and large panicles but long growing duration. The third was similar to the second group but with less number of panicles. The fourth group had middle stem with large number of panicles.
