  • GENETIC STUDIES AND IMPROVEMENT OF OFADA RICE LANDRACES (Oryza sativa L.) FOR REPRODUCTIVE STAGE DROUGHT TOLERANCE IN NIGERIA

    ABSTRACTDrought is the most important abiotic factor limiting rain-fed upland rice production in Nigeria. The intermittent and widespread occurrence of drought stress in rain-fed rice fields in sub-Sahara Africa has led to tremendous read more...

  • GENETIC STUDIES ON ORANGE-FLESHED SWEETPOTATO FOR HIGH DRY MATTER CONTENT AND RESISTANCE TO SWEETPOTATO VIRUS DISEASE

    ABSTRACTIn order to develop acceptable orange-fleshed sweetpotato (OFSP) to replace the low dry matter content and sweetpotato virus disease (SPVD)-susceptible varieties that are facing low adoption, studies were conducted to identify read more...

  • GENETIC IMPROVEMENT OF SORGHUM [SORGHUM BICOLOR (L.) MOENCH] FOR RESISTANCE TO [COLLETOTRICHUM SUBLINEOLIUM (P.) HENN] ANTHRACNOSE DISEASE IN BURKINA FASO

    ABSTRACTStudies were undertaken to ascertain the challenges that cause the low grain yield of sorghum in Burkina Faso, to assess the genetic diversity of the targeted germplasm, to assess the virulence of read more...

  • EARLY GENERATION SELECTION FOR DROUGHT RELATED TRAITS IN GROUNDNUT (Arachis hypogaea L.) IN MALI

    ABSTRACTGroundnut, an important food, feed and cash crop in the Sahel, is mostly rain-fed and most of the time, the growing phase terminates under a period of drought. This exposes the crop to end-of season drought, causing high yield losses. The main objective read more...

  • BREEDING SORGHUM (Sorghum bicolor L. Moench) FOR HIGH GRAIN YIELD AND RESISTANCE TO SORGHUM MIDGE (Stenodiplosis sorghicola Coquillett) IN NIGER

    ABSTRACT

    According to the results of rural appraisal, farming in the study sites was mainly smallholder family system. Farmers were predominantly young sorghum producers with low levels of read more...

  • GENETIC AND PHYSIOLOGICAL ANALYSIS OF FLOWERING IN CASSAVA (Manihot esculenta Crantz)

    ABSTRACT

    Due to increased utilisation and discovery of novel end products, the demand for cassava has increased significantly. Cassava breeders have the responsibility to release varieties with read more...

  • GENETIC STUDIES ON CYTOPLASMIC MALE STERILITY AND ANTHER INDEHISCENCE IN HYBRID RICE DEVELOPMENT

    ABSTRACT

    To evaluate the prospects of hybrid rice in Ghana, studies were undertaken, through participatory rural read more...

  • A STUDY OF GENETIC VARIABILITY AND QUANTITATIVE TRAIT LOCI (QTL) FOR SALINITY TOLERANCE IN RICE (Oryza sativa L.)

    ABSTRACT

    Sub-soil salinity is the leading physiological stress limiting rice productivity in inland and coastal regions of West Africa. Thus, rice productivity could be read more...
