The aim of this study was to investigate the role of Pseudotheraptus devastans in cassava anthracnose disease transmission and development. P. devastans, Dist (Het. Coriedae) insects were collected from cassava (Manihot esculenta Crantz) field plots at the International Institute of Tropical Agri...

Role of insect vector Pseudotheraptus devastans in cassava anthracnose disease development
La concurrence des mauvaises herbes est un obstacle à la rentabilité de la production du manioc. La connaissance des espèces de mauvaises herbes qui affectent négativement la productivité du manioc est essentielle pour une gestion efficace. Une étude a été conduite entre mai et juin 2014 et 2015 ...

Before implementation of genomic selection, evaluation of the potential accuracy of prediction can be obtained by cross-validation. In this procedure, a population with both phenotypes and genotypes is split into training and validation sets. The prediction model is fitted using the training set,...

Relatedness and genotype x environment interaction affect prediction accuracies in genomic selection: a study in cassava
Twenty-one yellow-fleshed cassava genotypes were evaluated over two years in five major cassava growing agroecological zones in Nigeria. The trials were established in a randomized complete block design with four replications to assess genotype performance and Genotype × Environment interaction f...

Cassava is an important starchy root crop and a major staple for more than 70 million people in Nigeria. New yellow-fleshed genotypes are being developed to combat vitamin A deficiency. Trials of 18 yellow-fleshed genotypes and two officially released white-fleshed clones, used as checks for 2008...

Despite its relatively recent introduction to Africa, cassava (Manihot esculenta Crantz) has become a major food crop adapted to a wide range of agro-ecologies that is grown by millions of small-holding farmers of sub-Saharan Africa (SSA), owing to its remarkable tolerance to an array of biotic a...

Cassava mosaic disease (CMD) is a viral disease of the important tropical staple crop cassava (Manihot esculenta) and preferred management involves use of host–plant resistance. The best available resistance is controlled by a single dominant gene. Serial analysis of gene expression (SAGE) was us...
