With these desirable characteristics, they may be regarded as resistant. Based on the results of this study, it is concluded that considerable variation in susceptibility exists among the local and improved genotypes, thus suggesting a
large range of genetic diversity is available within the germplasm and there is possibility of breeding cultivars that are resistant to CAD. Research institutes should supply the identified resistant cultivars to the farmers who do not have resistant planting materials for the next growing season at a reduced price. The selection and production of
cassava cultivars that are resistant to pest and diseases is a major priority towards meeting international challenges in food security, poverty alleviation, agricultural productivity and environmental conservation. More cultivars,
especially those resistant to other key diseases,
example, cassava mosaic disease (CMD), cassava
and bacterial blight (CBB), should be screened for
resistance. Farmers should be educated on the
advantages of using healthy stems and the risk
involved in transportation of infected planting
materials from one place to another.
