ABSTRACT

This chapter summarizes approaches at Asian Vegetable Research and Development Center in developing sweet potato varieties for tips. When the Philippines suffered serious flooding in 1972, only two green leafy vegetables could be regularly found in both urban and rural markets—sweet potato tips and water convolvulus or "Kangkong". Sweet potato vine tips had to be evaluated in the several ways in which conventional leafy vegetables have normally been evaluated. All other vegetables were destroyed by about a month's continuous rain. Tips in this context refer to that portion of the top used for human consumption. The strong flavor of tips make them less easy to cook with other vegetables. Tips are considered tough compared to other leafy vegetables. One of the most difficult tasks in encouraging greater use of sweet potato tips is to determine the different selection criteria to be used in predicting their general acceptability.
