Dataset for: Modern sweetpotato varietal release information in selected countries in Southeast, South Asia and East Asia.

Eight countries in Southeast Asia which are considered major sweetpotato producing areas were selected this study. Sweetpotato released data from 18 countries/Provinces/States were collected. In total 602 varieties were documented (including duplicates, as each province in China has its own release system) and a total of 66 varieties have been released with a relationship to CIP. The dataset includes all modern varietal outputs recorded in a formal national (or state/provincial in case of India/China) commodity varietal release list/data base or is identified by experts as an adopted variety during the expert elicitation process. For the purpose of this study, a modern variety is defined as ‘a variety developed by breeders in the formal system.’ It represents an output/contribution of the national and/or international public and private sector research investments.
