Tracking crop varieties using genotyping-by-sequencing markers: a case study using cassava (Manihot esculenta Crantz)

Autor: Rabbi, Ismail Y. Kulakow, P.A. Manu-Aduening, J.A. Dankyi, Ansong A. Asibuo, James Y. Parkes, Elizabeth Y Abdoulaye, Tahirou Girma, Gezahegn Gedil, Melaku A Ramu, Punna Reyes, Byron Maredia, Mywish K.

Accurate identification of crop cultivars is crucial in assessing the impact of crop improvement research outputs. Two commonly used identification approaches, elicitation of variety names from farmer interviews and morphological plant descriptors, have inherent uncertainty levels. Genotyping-by-...

Improving genomic prediction in cassava field experiments using spatial analysis

Autor: Elias, A.A. Rabbi, Ismail Y. Kulakow, P.A. Jannink, Jean-Luc

Cassava (Manihot esculenta Crantz) is an important staple food in sub-Saharan Africa. Breeding experiments were conducted at the International Institute of Tropical Agriculture in cassava to select elite parents. Taking into account the heterogeneity in the field while evaluating these trials can...

Genetic variation of postharvest physiological deterioration susceptibility in a cassava germplasm

Autor: Moyib, K.O. Mkumbira, J. Odunola, O. Dixon, A. Akoroda, M.O. Kulakow, P.A.

Postharvest physiological deterioration (PPD) is an unresolved major stress in cassava (Manihot esculenta Crantz), which constrains the crop suitability for commercial and industrial purposes. The present study sourced for PPD tolerance from different genetic resources available within a cassava ...

Accuracies of univariate and multivariate genomic prediction models in African cassava

Autor: Okeke, U.G. Akdemir, D. Rabbi, Ismail Y. Kulakow, P.A. Jannink, Jean-Luc

Background: Genomic selection (GS) promises to accelerate genetic gain in plant breeding programs especially for crop species such as cassava that have long breeding cycles. Practically, to implement GS in cassava breeding, it is necessary to evaluate different GS models and to develop suitable m...

Relatedness and genotype x environment interaction affect prediction accuracies in genomic selection: a study in cassava

Autor: Ly, D. Hamblin, M. Rabbi, Ismail Y. Gedil, M. Bakare, M.A. Gauch Jr. H. Okechukwu, R.U. Dixon, A. Kulakow, P.A. Jannink, Jean-Luc

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,...
