Cassava mosaic disease (CMD), caused by different species of cassava mosaic geminiviruses (CMGs), is themost important disease of cassava in Africa and the Indian sub-continent. The cultivated cassava speciesis protected from CMD by polygenic resistance introgressed from the wild species Manihot ...

Compared with other reduced-representation sequencing methods, library construction for genotyping-by-sequencing (GBS) is simpler and less expensive. However, elimination of sizeselection steps results in libraries of more variable fragment size than with other reduced-re...

The effects of restrictionenzyme choice on properties of genotypingbysequencing libraries: a study in cassava (Manihot esculenta)
Cassava (Manihot esculenta L.) is one of the most important food crops in the tropics, but yields are far below their potential. The gene pool of cassava contains natural genetic diversity relevant to many important breeding goals, but breeding progress has been slow, partly because of insuf-fici...

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
Cassava (Manihot esculenta Crantz) is a crucial, under-researched crop feeding millions worldwide, especially in Africa. Cassava mosaic disease (CMD) has plagued production in Africa for over a century. Biparental mapping studies suggest primarily a single major gene mediates resistance. To inves...
