An assessment of four pilot processing centers in Tanzania, established for processing cassava to high quality cassava flour, chips and starch based on IITA technologies was carried out from 2003 to 2005. We followed the value chain analysis approach, looking in detail at processing efficiency an...

Breeding cassava relies on a phenotypic recurrent selection that takes advantage of the vegetative propagation of this crop. Successive stages of selection (single row trial- SRT; preliminary yield trial – PYT; advanced yield trial – AYT; and uniform yield trials UYT), gradually reduce the number...

Two new mutant cassava starches with extreme amylose contents (0 and 30 31%) have been recently reported. These mutants are drastically different from normal cassava starch whose amylose content typically ranges between 15 and 25%. The new mutants were compared with five normal cassava starches (...

Life table studies were conducted to assess the effect of constant temperature on the rate of population growth of the cassava mealybug, Phenacoccus manihoti Matile‐Ferrero. Four temperatures, between 20 and 30.5 °C, were tested. An inverse relationship was observed between temperature and most d...
