Abstract

Sweet potato (Ipomoea batatas L.) embryos excised from the fertilized ovules of 6- to 12-day-old capsules were cultured on MS medium supplemented with NAA, BA, GA separately and in combinations. GA was found essential for initial morphogenesis of globular and heart stages. Seedlings were recovered from late globular stage onwards but recovery was best from advanced embryo stages. Differentiated embryos produced multiple shoots on MS medium +1μM NAA÷2μM BA +0.5μM GA.
