  • GENETIC IMPROVEMENT OF ROOT YIELD AND NUTRITIONAL QUALITY OF CASSAVA (Manihot esculenta Crantz) IN SIERRA LEONE

    ABSTRACT

    Cassava storage root is a major staple. However, the tuber is poor in nutrients especially micronutrients. The study was conducted to improve the nutritional status of cassava with farmers’ preferred read more...

  • GENETIC ANALYSIS OF DROUGHT TOLERANT EARLY MATURING WHITE MAIZE (Zea mays L.) INBREDS WITH STRIGA RESISTANCE GENES FROM Zea diploperennis

    ABSTRACT

    Recurrent drought and parasitism by Striga hermonthica Del. Benth constitute the two most important stresses limiting maize (Zea mays L.) production and productivity in sub- read more...

  • GENETIC CHARACTERISATION OF TOLERANCE TO FERROUS IRON TOXICITY IN WEST AFRICAN RICE CULTIVARS

    ABSTRACT

    Iron toxicity is one of the main constraints of lowlands rice production in West Africa. The adoption of tolerant varieties constitutes a sustainable approach to address this constraint. The objectives of this study were to: (i) assess the lowland read more...

  • GENETIC ANALYSES AND SELECTION STRATEGIES FOR IMPROVEMEMENT OF FARMER PREFERRED TRAITS IN CASSAVA

    ABSTRACT

    Cassava (Manihot esculenta Crantz) is a unique tuberous crop, income earner and highly valued carbohydrate source for close to a billion people especially in Africa. As food demands on the African continent are read more...

  • GENETIC ANALYSIS OF RESISTANCE OF COWPEA [Vigna unguiculata (L.) Walp.] TO Alectra vogelii Benth. IN BURKINA FASO

    ABSTRACT

    Alectra vogelii is a parasitic weed of the Schrophulariaceae family causing severe damage to cowpea in Southern, Eastern and Western Africa. Total yield losses occur in heavily infested fields. In read more...

  • GENETIC VARIABILITY FOR DROUGHT TOLERANCE IN COWPEA RECOMBINANT INBRED LINES [Vigna unguiculata (L.) WALP.] IN GHANA

    Abstract

    Drought is more prevalent in the semi-arid areas where cowpea has the greatest potential. It is unpredictable in occurrence so timing to avoid drought is not easy. Drought affects both vegetative read more...

  • SELECTION OF COWPEA (Vigna unguiculata (L). Walp) FOR HIGH YIELD UNDER LOW SOIL PHOSPHORUS CONDITIONS

    ABSTRACT

    Nitrogen (N) and phosphorus (P) are among the main edaphic factors that limit crop production in Sub-Saharan Africa (SSA). As a nitrogen fixing legume, cowpea production is not significantly affected by N, but P read more...

  • ASSOCIATION MAPPING AND STABILITY ANALYSIS OF RESISTANCE TO CASSAVA GREEN MITE IN CASSAVA (Manihot esculenta Crantz)

    ABSTRACT

    Cassava is a unique crop, because it is the primary source of carbohydrate for more than 1 billion people. In Nigeria, cassava has become a major sustenance crop and currently and is the world’s largest producer of read more...

  • GENETIC ANALYSIS FOR HIGH STARCH, DRY MATTER CONTENT AND STORAGE ROOT YIELD IN CASSAVA (Manihot esculenta Crantz) 

    ABSTRACT

    Although cassava (Manihot esculenta Crantz) has benefited from a significant amount of research, there read more...

  • EMPIRICAL VALIDATION OF GENETIC GAINS OF GENOMIC SELECTION IN CASSAVA (Manihot esculenta Crantz) BREEDING

    ABSTRACT

    The success of a genetic breeding program can be assessed by the genetic gain obtained and successful varieties released. The validation of genomic selection (GS) efficacy in cassava (Manihot read more...
