  • GENETIC CONTROL OF SUGARS, DRY MATTER AND BETA-CAROTENE IN SWEETPOTATO (Ipomoea batatas [L.] Lam), ABSTRACT

    Sweetpotato has immense potential for food and nutrition security in Ghana. It is however, infrequently used in local cuisines. Breeders have attributed this low utilization to the fact that sweetpotato lacks quality read more...

  • GENETIC ANALYSIS OF RESISTANCE TO ROSETTE DISEASE OF GROUNDNUT (Arachis hypogaea L.), ABSTRACT

    Groundnut rosette disease (GRD), transmitted naturally by aphids, Aphis craccivora, is the most destructive viral disease of groundnut (Arachis hypogaea L.) in Nigeria and causes serious yield losses to farmers. The narrow genetic base among read more...

  • GENETIC IMPROVEMENT OF ALKALINITY TOLERANCE IN RICE IN OFFICE DU NIGER IN MALI, ABSTRACT

    Alkalinity stress is one of the most important abiotic stresses limiting rice production in irrigated systems. Alkalinity stress during seedling stage widely affects irrigated rice production of Office du Niger in Mali. The development of rice cultivars that tolerate alkalinity stress condition has been read more...

  • GENETIC ANALYSIS OF POSTHARVEST PHYSIOLOGICAL DETERIORATION IN CASSAVA (Manihot esculenta Crantz) STORAGE ROOTS, ABSTRACT

    Postharvest physiological deterioration (PPD) is a serious abiotic stress in cassava that renders the roots unmarketable, thereby reducing the economic value of the crop. This study was undertaken to determine read more...

  • GENETIC ANALYSIS FOR PANICLE ARCHITECTURE AND GRAIN YIELD IN SORGHUM [Sorghum bicolor (L.) Moench] IN MALI, ABSTRACT

    Sorghum panicle architecture is a complex trait involving growth, elongation and branching pattern. The main objective of this research was to determine the genetic control of sorghum panicle architecture and its read more...

  • GENETIC CHARACTERIZATION, ASSOCIATION MAPPING AND EVALUATION OF HETEROTIC PATTERNS OF TROPICAL MAIZE (Zea mays L.) INBRED LINES UNDER DROUGHT AND NON-DROUGHT CONDITIONS, ABSTRACT

    Genetic diversity provides the capacity for plants to meet changing environments and farmers' preferences, and to establish heterotic patterns, essential for read more...

  • DR. TRAORE VALENTIN STANISLAS EDGAR MARKER ASSISTED SELECTION FOR RESISTANCE TO RICE YELLOW MOTTLE VIRUS IN FARMERS’PREFERRED RICE VARIETIES IN BURKINA FASO, ABSTRACT

    Rice yellow mottle disease (RYMD), caused by Rice yellow mottle virus (RYMV), is a very damaging disease of rice in Sub-Saharan Africa. A participatory rural appraisal was conducted in Burkina Faso to assess farmers' awareness of read more...

  • GENETIC ANALYSIS OF EARLINESS AND DROUGHT TOLERANCE IN GROUNDNUT (Arachis hypogaea L.) IN NIGER, ABSTRACT

    End-of-season drought, characterized by low and erratic rainfall, is the most important factor limiting groundnut (Arachis hypogaea L.) production in Niger. Information about farmers' varietal preferences and production constraints read more...

  • GENETIC ANALYSIS OF STRIGA RESISTANCE AND LOW SOIL NITROGEN TOLERANCE IN EARLY MATURING MAIZE (Zea mays L.) INBRED LINES, ABSTRACT

    Striga hermonthica (Del.) and low soil nitrogen (low N) are among the most important constraints to maize production and productivity in West Africa (WA). Knowledge and understanding of the inheritance of read more...

  • DEVELOPMENT OF TOPCROSS HYBRID MAIZE (Zea mays L.) FOR YIELD AND RESISTANCE TO MAIZE STREAK VIRUS DISEASE, ABSTRACT

    Studies were conducted to explore the potential of utilizing Ghanaian maize landraces for improved grain yield and resistance to the maize streak virus disease. Farmer perceptions of the maize streak virus disease as well read more...
