【 摘 要 】

Study of the behaviour in the field and of local varieties performances of sweet potato Ipomoea batatas in eastern Zaire. The most cultivated twenty local varieties of Sweet Potato in Ituri District have been put in competition al INERA-NIOKA Research Center in order to compare their performances. Five of them have been eliminated during undergoing trials owing to their low productivity. The Kenya variety with yellowish skin and yellow flesh has proved itself to be resistant to viroses attacks with a produre and a very high number of tubers. Again, given its very short vegetative cycle (about four months) this variety can be used as a witness in further trials with exotic materials.
