  • GENETIC ANALYSIS OF GRAIN QUALITY TRAITS IN RICE, ABSTRACT

    The study was undertaken to assess farmer and consumer perceptions on grain quality preferences, characterize (physicochemically and with gene markers) rice germplasm from Africa and the U.S.A for their quality, map QTLs for grain quality and agronomic traits in a BC1F2 population derived from a cross between Digang and Jasmine 85 read more...
  • GENETIC IMPROVEMENT OF SWEETPOTATO (Ipomoea batatas [L.] Lam) FOR BETA-CAROTENE AND YIELD IN BURKINA FASO, ABSTRACT

    The potential of sweet potato to address food security, malnutrition and poverty is acknowledged in Sub-Saharan Africa. The present study was undertaken to develop varieties combining yield and quality in order to address read more...

  • BREEDING COWPEA (Vigna unguiculata (L). Walp) FOR PHOSPHORUS USE EFFICIENCY IN GHANA, ABSTRACT

    A participatory rural appraisal (PRA) survey was conducted to elicit farmers‘ perceptions on soil fertility (especially soil phosphorus) and to gather information on elite cowpea varieties. Later, field studies were conducted to (a) screen read more...

  • IMPROVING BETA-CAROTENE CONTENT IN FARMERS’ PREFERRED CASSAVA CULTIVARS IN NIGERIA, ABSTRACT

    The study was conducted to assess the potential to improve farmers’ preferred cassava cultivars with high carotene content in Nigeria. A participatory rural appraisal (PRA) and sensory evaluation was conducted in Abia, Imo and Ebonyi states of Nigeria to identify farmers’ and consumers’ adoption read more...

  • GENETIC ANALYSES OF DROUGHT TOLERANCE IN CROSSES OF ADAPTED AND EXOTIC MAIZE (Zea mays L.) INBRED LINES, ABSTRACT

    Molecular-marker-based genetic distances, pedigree information, and estimates of genetic effects are often combined to select parents of superior high yielding hybrids. The objectives of this study were to:

  • STABILITY FOR GRAIN YIELD PERFORMANCE OF MAIZE INBREDS AND THEIR HYBRIDS IN VARYING DROUGHT STRESS ENVIRONMENTS IN MALI, ABSTRACT

    Hybrid maize varieties have not yet been adopted by many farmers in Mali. This is partly due to the lack of good hybrid varieties that are tolerant to drought. Recurrent drought is one of the major constraints to maize production in West Africa. It can be read more...

  • DEVELOPMENT OF DOWNY MILDEW RESISTANT, F1 PEARL MILLET (Pennisetum glaucum ( L.) R. Brown) HYBRIDS IN NIGER, ABSTRACT

    With rapid population growth, continued improvement for yield of pearl millet, the first staple cereal in Niger, is a major priority. It is also necessary to integrate local community needs in technology development read more...

  • EVALUATION OFNIGERIEN SORGHUM [Sorghum bicolor (L.) Moench] LANDRACES AND THEIR TESTCROSS HYBRIDS FOR COMBINING ABILITY ABSTRACT

    The development of successful improved sorghum varieties for the Western Africa requires the incorporation of farmer’s perceptions and desires into the end product. Failure to do this in the past probably read more...
