The comprehensive analysis on present situations and resource characteristics of Guangxi Litchi were employed to show that the main limiting factors to sustainable development of Guangxi Litchi industry were unreasonable variety structure, the excessive concentrates of time to market, less input, extensive management, unstable yield. The survey of 156 farmers from different areas showed that prematurity, high quality and stable yield, storability and transport, matching technology of Litchi varieties were preferred. For it, the paper was designed to propose measures to breeding and research of Litchi varieties, and make the 12th five-year-plan scheme (2011-20
