Other aspect were the association among characters in cassava, the use of genetic markers in cassava improvement, the effect of mosaic virus disease on chlorophyll content of cassava, and cassava starch. It focuses on the basic tools for genetic diversity analysis, significance of genetic variation and the use of PCR based technique for screening for cassava mosaic virus disease resistance. Researchers interested in tropical root crops, and starch industries will benefit immensely from this work.
