accessions R12, R14 and Kakamega 5 despite the low yields suggest that these accessions could be candidates in a breeding program for resistance to stunting disease. The cause of stunting disease is phytoplasma which are mainly transmitted through use of infected planting materials and insect vectors. The findings of the present study was based on the hypothesis that insects feeding on the diseased surrounding material will also feed on the healthy accessions planted in the middle and hence transmit the phytoplasma. This was purely based on a chance scenario. In order to find a long term solution of variety/varieties resistant to stunting disease, there is need for the following studies to be undertaken. To collect and identify the insect vector species involved in the transmission of the stunting disease. Study the mechanism of transmission by vectors, Napier cultivars/accessions preference by vectors, seasonal fluctuations, and biology (life cycle) and identify stages of the insect which transmit the disease. Identify the best vector for transmission of the disease so that it can be used to transmit the disease and select varieties, which are resistant or tolerant under bio-containment. Use tissue culture techniques to produce clean disease free Napier planting materials from those identified to be resistant. Develop integrated management strategies to reduce the incidence of the disease and its spread.
