Performance of Selected Sweet Potato Germplasms under Egyptian Conditions.

Sweet potato (Ipomoea batatas) is a promising crop in Egypt for both local consumption and export market. The aim of this work was to introduce, evaluate and select a number of promising sweet potato cultivars under Egyptian conditions. Nine sweet potato germplasm materials, namely CIP- 440189, CIP- 199026.1, CIP-400011, CIP- 400004, CIP- 420009, CIP-199015.14, - CIP- 199004.2, CIP-440093 and CIP-1999062.1 were tested under Egyptian conditions. The evaluation was based on high yield, flesh colour and nutritional value (Beta- carotene, starch, mono sugar and total soluble sugar). Results showed that the four sweet potato germplasm, namely, CIP-199004.2, CIP- 440189,CIP- 440093 and CIP- 199026.1 are promising cultivars and gave the highest yield, beta carotene, starch, mono sugar and total soluble sugar in comparison with others sweet potato germplasm.
