Plant breeding consists in the creation and selection of new genotypes. This involves not only keeping records across generations and environments but also accommodating data of increasing resolution on genotypes, phenotypes, and growth environments. Some such high-resolution characterization met...
Dioscorea alata L. is a highly important crop, widely distributed in the humid and semi-humid tropics. Flow cytometry was used to determine the ploidy levels of 74 D. alata genotypes collected mainly from West African countries. Sixty three of the genotypes were found to be tetraploid, one was he...
The Tropical Legumes II (TL II) project, funded by the Bill & Melinda Gates Foundation, aims to improve the lives and livelihoods of smallholder farmers in the drought-prone areas of Sub-Saharan Africa (SSA) and South Asia (SA) through improved productivity and production of six major tropical le...
Sweetpotato (Ipomoea batatas L. (Lam)) is a nutritious food security crop for most tropical households, but its utilisation is very low in Ghana compared to the other root and tuber crops due to lack of end-user-preferred cultivars. Knowledge on the genetic control of important traits such as dry...
Over the past 15 years, biofortification, the process of breeding nutrients into food crops, has gained ample recognition as a cost-effective, complementary, feasible means of delivering micronutrients to populations that may have limited access to diverse diets, supplements, or commercially fort...
Crop biofortification is a cost-effective and sustainable agricultural trategy to reduce micronutrient malnutrition arising from iron (Fe) and zinc (Zn) deficiencies. A large number of hybrids and open-pollinated varieties (OPVs) of pearl millet [Pennisetum glaucum (L.) R. Br.] have been release...
A multilocational evaluation trial comprising 18 Musa genotypes was carried out from 1991to1994 in three respective locations in Humid Forest (Onne, Nigeria and M' Balmayo, Cameroon) and the Forest- Savanna Transition (Ibadan, Nigeria) zones of West and Central Africa.
Une essai multilocal comprenant 18 genetype de Musa a ete counduit de 1991 a 1994 dans 3 sites representatives dan la foret humide (Onne, Nigeria and M'Balmayo, cameroun) et dans la zone de transition Foret-Savanne (Ibadan, Nigeria) en Afrique de l'Ouest et Centrale.
Ploidy polymorphism occurs in the hybrid offspring derived from interspecific crosses between triploid plantains (Musa spp. AAB group) and diploid bananas (M. acuminata). Therefore, Musa breeders are interested in the determination of ploidy and its effects on phenotypic expression of quantitativ...
