This review article discussed the neutral genetic topics related to cassava (Manihot esculenta Crantz) variation, evolution, genetic resources and domestication leading to the remarkable differences in cassava storage root traits that could be used to improve human nutrition’s qualities for food supply in tropical regions of the world. Updated information on genetic resources, genetic diversity, genomics, transcriptomic, proteomics, and metabolism pathways to improve cassava storage root traits throughout conventional breeding was provided. Procedures results and achievements were presented to illustrate the improvements on novel starch content, protein content and carotenoid content as well as conventional breeding of cassava storage roots.

Key words: cassava, storage root, nutritional quality, genetic resources, genetic diversity, conventional breeding
