Major area is maize genetics and genomics while QTL mapping of complex traits of rice and maize using RIL/MAGIC population as well as fine mapping of major QTL trailed by prediction and positional cloning of candidate gene is the top priority expanse. Moreover, Genome Wide Furthermore, Development of mapping population (MAGIC and RIL) for QTL analysis in different crop plants and perfection of experimental hybrid surveyed by heterosis analysis is the thrust extent of current research.
