  • GENETIC ANALYSIS OF DROUGHT TOLERANCE IN COWPEA - ABSTRACT

    The potential of cowpea to address food security in Burkina Faso in particular is well established. However, there is limited information on drought tolerance and diversity in the germplasm in Burkina Faso and farmers’ perceptions on the effects of drought and their varietal preferences are not known. The present study was, read more...

  • DEVELOPMENT OF HIGH-YIELDING AND STABLE MAIZE (ZEA MAYS L.) HYBRIDS TOLERANT TO ACID SOILS OF THE TROPICAL HUMID FOREST ZONES OF CAMEROON - ABSTRACT 

    Maize is the most important cereal produced in the Bimodal Humid Forest Zone (BHFZ) of Cameroon. Yield of the crop in the BHFZ is very low because of the negative impact of soil acidity on plant growth. Lime increases soil pH levels to read more...

  • GENETIC STUDIES ON SALT TOLERANCE IN RICE (O. SATIVA) USING CONVENTIONAL AND MOLECULAR METHODS - ABSTRACT

    Niger’s rice production has not been able to match growth in demand. The slow growth in domestic rice production has been attributed to salinity, non-adapted germplasm, and low farmer adoption of improved varieties. This study was carried out to: determine farmers’ perception on read more...

  • BREEDING FOR GRAIN QUALITY TRAITS IN COWPEA [VIGNA UNGUICULATA (L) WALP] - ABSTRACT

    This study was conducted in Nigeria to: (i) assess farmer and consumer perceptions and preferences on grain quality traits in cowpea (ii) assess the variability of grain nutritional values (protein, iron and zinc content) of cowpea accessions from Africa and other parts of the world; (iii) determine the read more...

  • COMBINING ABILITY AND YIELD PERFORMANCE STUDIES OF TROPICAL MAIZE (ZEA MAYS L.) GERMPLASM UNDER DROUGHT STRESS AND WELL-WATERED ENVIRONMENT - ABSTRACT

    Maize is increasingly consumed by Nigerien households. Limited studies have been conducted on the production and productivity of this crop in Niger and very few cultivars (mostly open pollinated varieties) are available to farmers. read more...

  • GENETIC STUDIES OF PHYSIOLOGICAL AND MORPHOLOGICAL TRAITS ASSOCIATED WITH DROUGHT TOLERANCE IN CASSAVA GENOTYPES - ABSTRACT

    Breeding crops tolerant to abiotic constraints is more efficient if key traits that are closely related with yield are available for screening. This study was undertaken to identify key traits that are closely related to cassava yield under drought stress and also read more...

  • GENETIC ANALYSIS OF TOLERANCE TO LOW SOIL NITROGEN IN INTERMEDIATE MATURING MAIZE (ZEA MAYS L.) INBRED LINES - ABSTRACT

    Low soil nitrogen (N) is one of the most important constraints to maize production in sub- Saharan Africa (SSA) in general and the Bimodal Humid Forest Zone (BHFZ) of Cameroon. External source of N as nutrient are therefore required for increased yield of the crop. read more...

  • GENETIC CONTROL AND BREEDING FOR SEED SIZE AND COLOUR IN COWPEA [VIGNA UNGUICULATA (L.) WALP] - ABSTRACT

    Consumer preference is very important in acceptance of an improved crop variety. Participatory rural appraisal (PRA) was therefore, conducted, on preferred traits of cowpea [Vigna unguiculata (L)  Walp] among Ghanaian consumers in Ketu North, Ho and Akatsi districts. It was read more...

  • DEVELOPMENT OF END-USER PREFERRED SWEETPOTATO VARIETIES IN GHANA -ABSTRACT

    Sweetpotato has great potential as a food security and income generating crop as well as, raw material for industry in Ghana. In spite of its great potential to alleviate food insecurity, malnutrition and poverty, it has remained an untapped resource in Ghana as its level of utilization is very low. Studies were read more...

  • GENETIC ANALYSIS AND MARKER ASSISTED BREEDING FOR DROUGHT TOLERANCE AND YIELD IN CHICKPEA (CICER ARIETINUM L.) -  ABSTRACT

    Chickpea is an important legume crop in the arid and semi-arid lands (ASALs). It is commonly grown during the post-rainy season under receding soil moisture conditions. This exposes the crop to drought especially terminal drought which occurs towards the read more...
