Abstract:

Cassava(Manihot esculenta Crantz)is an important food crop, cash crop and energy crop in global tropical regions, but the biology research and breeding progress have lagged behind major food crops. Molecular breeding is the important driving force for cassava genetic improvement. Discovery the genes related to important traits is the foundation and premise for the transformation from traditional breeding to molecular breeding. In this paper, systematically, we recapitulate recent progress on the genes related to the traits, such as plant morphology, yield, tuber quality, stress resistance, in cassava, also functional characterization of some genes. We further point out that both of constructing self-crossing population and multiple-omics data integrated are important ways to discovery the key genes in cassava in the future. This paper aims to provide reference for promoting the application of results of functional genome studies in the construction of cassava breeding technology system, and provide theoretical guidance for cassava genetic improvement.

Key words: cassava, important trait, gene discovery, molecular marker, functional gene
