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...

Field evaluation of six cassava genotypes for resistance to root rot disease was compared with three rapid laboratory methods (whole root inoculation, root slice inoculation, and stem inoculation) for resistance screening. Both the field evaluation and the three laboratory methods separated the v...

Plant breeding efforts in sub-Saharan Africa (SSA) have produced biofortified cassava with high carotenoid content to address vitamin A deficiencies (VAD). Since carotenoids in foods are easily depleted during processing, the retention of β-carotene in some newly released cassava varieties is und...

As a case study to document the current characteristics of cassava mosaic virus disease (CMD) in post epidemic areas, surveys were carried out, in 2003 and2004, in Siaya District of western Kenya. This was an area affected by a severe CMD pandemic in the late 1990s. Data recorded on cassava varie...

Cassava clones CH92/082, TME 6 and BA95/070 were evaluated against Mbundumali, Phoso, Mulola and Sauti as checks. These clones were evaluated at Makoka, Mkondezi, Baka and Kasinthula Research Stations that represented different agro ecologies and in Mzuzu ADD under farmers' conditions. The object...

Genotype (G) by environment (E) interaction (GEI) in cassava was studied using 10 genotypes in a multilocational trial in Uganda at different altitudes for 2 years. The study investigated the magnitude of GEI and diagnosed the underlying causal factors of the G × E pattern. The ana...
