In vitro propagation of 2 selections of white-fleshed sweet potato (Ipomoea batatas (L.) Lam) was obtained on modified Murashige and Skoog media using lateral buds and shoot apices as primary explants. Cultivars differed in response to exogenous levels of growth substances and in rate of proliferation. Optimum shoot regeneration from ‘White Star’ explants was induced by 1 mg/liter benzyladenine (BA) and from Plant Introduction (PI) 315343 by 1 mg/liter kinetin with 1 mg/liter indoleacetic acid (IAA).
