Abstract:
The African cassava mosaic virus and cassava mealybug are devastating the cassava crop in Uganda. Because of the severe and widespread occurrence of the virus and mealybug, in vitro cultured cassava plantlets instead of stem cuttings will be irradiated. In addition, the project has incorporated sweet potato. Installation of tissue culture laboratory at Namulonge was completed in early 1993. Work is in progress to establish efficient in vitro culture micropropagation techniques for the two crops. Small numbers of cassava plantlets of varieties TMS 30337 and TMS 4(2)1425' and sweet potato entry 39 are in vitro culture. Mass irradiation of plantlets is planned in future
