  • GENETIC IMPROVEMENT OF RICE (Oryza spp.) FOR YIELD AND AROMA IN TOGO     ABSTRACT   In Togo, the quantity of rice produced is very low compared to the needs. Farmers and consumers prefer aromatic rice. With a view to increase the local production and supply farmers with aromatic and higher yielding lines, this research was conducted to lay the foundation of a rice breeding programme in the read more...
  • MOLECULAR CHARACTERIZATION AND HETEROSIS OF EXTRA-EARLY MATURING ORANGE MAIZE INBRED LINES UNDER CONTRASTING ENVIRONMENTS

     

    ABSTRACT Striga hermonthica and drought are major threats to maize (Zea mays L.) productivity and productiopn in savannas of sub-Saharan Africa (SSA), a sub-region known to be plagued with vitamin A read more...
  • GENETIC DIVERITY AND BREEDING OF Solanum aethiopicum SHUM GROUP FOR DROUGHT TOLERANCE

     

    ABSTRACT Solanum aethiopicum is one of the most important Solanum species, with four morphological groups. Two of the groups, Gilo and Shum, are mainly cultivated because of their nutritional value and income generating potential for read more...
  • GENETIC STUDIES AND QTL MAPPING OF DROUGHT RELATED TRAITS IN A SWEETPOTATO (Ipomea batatas(L.) BI-PARENTAL MAPPING POPULATION

     

    ABSTRACT The study was carried out to understand the genetic basis for yield under drought environments, and to map quantitative trait loci associated with yield and yield related components under read more...
  • GENETIC IMPROVEMENT OF COWPEA (Vigna unguiculata L. WALP) FOR EARLINESS AND DROUGHT TOLERANCE IN SOUTH SUDAN

     

    ABSTRACT The number of people suffering from chronic undernourishment in sub-Saharan Africa has increased. The potential of the cowpea to be the crop of the future to address food and nutrition insecurity is evident read more...
  • BREEDING OPTIONS IN GENETIC AND GENOMIC RESOURCES TO IMPROVE RESILIENCE TO STRIGA [Striga gesnerioides (Wild.) Vatke] AND DROUGHT IN COWPEA

     

    ABSTRACT   Cowpea (Vigna unguiculatan (L.) Walp.) is a grain legume cultivated worldwide over 14 million ha. Striga resistance is an important trait that is missing to most cultivated read more...
  • GENETIC IMPROVEMENT OF COWPEA (Vigna unguiculata (L.) WALP) FOR PHOSPHORUS USE EFFICIENCY

     

    ABSTRACT   Cowpea is an important grain legume crop for millions of humans, fodder for livestock and income for all value chain actors. Its productivity is constrained by several biotic and abiotic stresses such as drought and poor read more...
  • IDENTIFICATION OF SOURCES AND LOCI FOR DEVELOPMENT OF SOYABEAN [GLYCINE MAX (L.) MERR] CULTIVARS THAT COMBINE BACTERIAL PUSTULE AND SEED DECAY RESISTANCE WITH HIGH POD CLEARANCE

     

    ABSTRACT   Globally, diseases constitute a major biotic constraint to soyabean production. Although, some information on diseases of soyabean in read more...
  • DEVELOPMENT OF HIGH YIELDING TOMATO (Solanum lycopersicum L.) LINES WITH RESISTANCE TO TOMATO YELLOW LEAF CURL DISEASE (TYLCD).

     

    ABSTRACT   Tomato (Solanum lycopersicum L.) is the most important vegetable in Ghana in terms of area under cultivation and consumption, but production is challenged by lack of improved cultivars read more...
  • GENOMIC STUDY AND GENETIC IMPROVEMENT OF SORGHUM [Sorghum bicolor (L) MOENCH] FOR HIGH PROTEIN DIGESTIBILITY

     

    ABSTRACT   Sorghum is a staple crop and a major source of food and energy for the World’s developing countries. However, its utilization as human food is constrained by the low availability of its proteins after wet read more...
