Diversity and genome-wide association mapping of farmer preferred traits yam genetic resources in Uganda
Amponsah, Emmanuel Adjei (Makerere University, 2023-04-03)Although yam is a very important crop with the potential to address future food insecurity resulting from challenges due to climate change and increasing world population, its potential has largely remained unexploited in ... -
Genetic diversity and population structure of Uganda’s yam (Dioscorea spp.) genetic resource based on DArTseq
Amponsah, Emmanuel Adjei (Public Library of Science, 2023-02-14)Assessing the genetic diversity of yam germplasm from different geographical origins for cultivation and breeding purposes is an essential step for crop genetic resource conservation and genetic improvement, especially ... -
Genotype-by-environment interaction of yam (Dioscorea species) for yam mosaic virus resistance, dry matter content and yield in Uganda
Amponsah, Emmanuel Adjei; Esuma, Williams; Alicai, Titus; Boache, Emmanuel Chamba; Edema, Richard; Onziga, Isaac Dramadri; Adebo, Alfred Ozimati; Agaba, Rolland; Odong, Thomas L. (MDPI, 2022-08-23)Often, yam cultivars grown in different agro-ecologies show differential responses across production environments, a term known as "genotype-by-environment interaction. Such genotype-by-environment interaction makes the ... -
Phenotypic diversity within Ugandan yam (Dioscorea species) germplasm collection
Amponsah, Emmanuel Adjei; Esuma, Williams; Alicai, Titus; Bhattavharjee, Ranjana; Onziga, Isaac Dramadri; Agaba, Rolland; Boache, Emmanuel Chamba; Odong, Thomas L. (Hindawi, 2022-12-19)A proper understanding of the diversity of the available germplasm is an initial step for the genetic improvement of a crop through breeding. However, there is limited information on the diversity of Uganda’s yam germplasm. ...
