The present communication is aimed to find out determinants of molecular marker based classification of rice (Oryza sativa L) germplasm using the available data from an experiment conducted for development of molecular fingerprints of diverse varieties of Basmati and non Basmati rice adapted to irrigated and aerobic agro-eco systems. The distance-matrix based dendrogram was developed following UPGMA method that grouped all the 44 varieties agro-eco systems wise. We examined the clustering of Basmati and non- Basmati varieties in detail. The results suggest that the easily distinguishable simple characters viz. plant height, photosensitivity, leaf color, awn’s color, awns’ number etc., governed by major genes did not contribute significantly towards classification of rice genotypes used. The complex characters such as adaptation to agro-eco systems and rice quality may play vital role in determination of molecular marker based classification of rice genotypes. Key word: Basmati rice, molecular markers, genetic diversity, agro-eco systems, rice quality
