First Evaluation of Taro (Colocasia esculenta) Genotypes Against Leaf Blight (Phytophthora colocasiae in Ghana

Taro genotypes were collected and evaluated to determine their resistance in the Aowin Suaman district of Ghana. Twenty five (25) genotypes of taro from both the Ashanti and Western Region were evaluated for six months in a location for resistance to the leaf blight disease in the study area. The Randomized Complete Block Design was used with each accession replicated three times. The results revealed that of the 25 accessions evaluated, no accession was completely resistant to the disease in the study area, though some were moderately resistant, and that the only solution to the disease is to breed for resistance.
