Sweet potato [Ipomoea batata (L.) Lam.] is an important root crop in the Caribbean. In 1998 a selection program was established to evaluate landraces and accessions from the USD A Plant Germplasm System, for horticultural traits and adaptability to conditions in the Caribbean. Tuber number fluctuated from 49,056 to 97,170 /ha and yields ranged from 28,577 to 57,798 kg/ha. Analysis of variance showed significant differences for accession and time of harvest but not for the interaction between accession and harvest time. Accession 98-023 produced the highest yield, but root deformation may limit its commercial acceptance. Accession 98-022 and 97-031 produced 43,173 and 43,500 kg/ha, respectively, and have good tuber shape, high quality flesh appearance and good flavor. All of the accessions evaluated in this experiment are susceptible to the sweet potato weevil.
