Genetic Diversity, Correlation and Path Analyses of Okra (Abelmoschus spp L. Moench) Germplasm collected in Ghana.

Abstract Thirty (30) accessions of okra (Abelmoschus spp. (L.) Moench) germplasm were collected from four major production regions in Ghana and were evaluated under field conditions at the Department of Horticulture, Kwame Nkrumah University of Science and Technology, KNUST, during the minor and major seasons of 2008 and 2009. The International Plant Genetic Resources Institute […]

Total Flavonoid, Phenolic Contents & Antioxidant Scavenging Activity in 25 accessions of Okra (Abelmoschus spp L.).

Abstract Twenty-five (25) accessions of Okra (Abelmoschus spp L.) were collected from eight geographic regions of Ghana and were evaluated for their phytochemical constituents. The objective of the study was to assess total flavonoid, phenolic and antioxidant activity in the accessions. Results indicate that, there are statistically significant differences (p≤0.05) in Total Flavonoid Contents (TFCs), […]

Biochemical Characterisation of 18 Accessions of Sweet Potato (Ipomoea  batatas L. Lam) Using Total Leaf &Tuberous Root Protein by SDS-PAGE

Abstract DNA-based markers, undeniably, provide potent tools for studying genetic relationships in plants; however, potential of protein-based markers using SDS-PAGE is quite promising, particularly in developing countries. Plant storage proteins serve as molecular reserves imperative for plant growth and maintenance and thus have proven to be essential for the survival of plant species. Storage proteins […]

Destination Distributor Selection & Relationship Management by SMEs involved in Non-Traditional Exporting: A Case Study of Three SMEs in Ghana

Abstract A survey was conducted to ascertain approaches adopted by small and medium enterprises (SMEs) to assess selection criteria and challenges of managing foreign distributor relationship in marketing of non-traditional exports (NTEs) from Ghana. Praise Export Services Ltd (PESL), Nature’s Best Fruits and Juices Ltd (NBFJL) and A1 Secko Farms (A1SF), a subsidiary of Secko […]

Essential Mineral Elements Profile of 22 Accessions of Okra (Abelmoschus spp L.) from Eight Regions of Ghana

  Abstract Five (5) essential macro, three (3) micro and two (2) trace mineral elements were determined in fresh fruits of twenty-two (22) accessions of okra using Instrumental Neutron Activation Analysis (INAA). These were correlated to assess the level of associations existing between these elements. Concentrations of these elements were juxtaposed with their recommended daily […]

Mucilage Content of 21 Accessions of Okra (Abelmoschus spp L.).

Abstract Twenty one (21) accessions of okra (Abelmoschus spp L.) were collected from eight geographical regions of Ghana and were studied for their mucilage content using Brabender Viscograph E. Fresh fruits of the accessions were harvested and mucilage extracted using improvised cold maceration method. The means of maximum viscosity ranged from 53.0 to 366.8 bu […]

Genetic Diversity Studies of 29 Accessions of Okra (Abelmoschus spp L.) Using 13 Quantitative Traits

Aims: Twenty nine (29) local and exotic lines (accessions), of okra (Abelmoschus spp L.) were evaluated for variation in phenotypic traits.   Study Design: They were laid out in a Randomised Complete Block Design (RCBD) with four replications and evaluated based on 13 quantitative characters.   Place and Duration of Study: Research farm of the […]

Detection of TYLCV in Ten Genotypes of Tomato (Solanum spp L.) using Serological and Molecular Techniques in a Coastal Savanna Zone of Ghana.

  Abstract Use of resistant varieties is a proven way of controlling the tomato yellow leaf curl virus (TYLCV), which causes a devastating disease of tomato in tropical and warm temperate regions, resulting in significant yield losses. However, breeding for resistant varieties is slow due to lack of effective methods of virus detection that will […]

Agromorphological Characterisation of 29 Accessions of Okra (Abelmoschus spp L.).

Abstract The West African sub-region is indisputably the region of greatest diversity of okra (Abelmoschus spp L.) germplasm as it currently hosts some 1,769 accessions of okra (representing 77.49%) out of the 2, 283 reported world-wide. These are largely uncharacterised, making it practically impossible to ascribe specific attributes to known accessions to facilitate breeding for […]

Phenotypic Profiles of Different Accessions of Sweet Potato (Ipomoea batatas L. Lam) in the Coastal Savanna Agro-Ecological Zone of Ghana.

Abstract Twenty (20) accessions of sweet potato (Ipomoea batatas L. Lam) cultivated under rain-fed conditions were evaluated based on their agromorphological traits to assess diversity in yield, morphology and other key agronomic characteristics of the accessions under study. The accessions consisted of 13 local and 7 exotic breeding lines grown in the research farm of […]
