Principal Component Analysis on 292 Oryza sativa sub. japonica tropical accessions from Asia and Africa: This figure shows the dimensional structuring of GJ-trp based on their geographical origins (by shape and colour) on axes 1 and 2 (a), and on axes 1 and 3 (b). The first three dimensions explain 29% of the total variance. (c) Percentage of explained variance for the first ten principal components
