Intra-Specific Hybridisation And Performance Evaluation Of Hybrid Lines Of Roselle (Hibiscus Sabdariffa L.)

ABSTRACT Roselle (Hibiscus sabdariffa L.) is an important multi-purpose crop in Ghana and across West Africa, used as a source of food as well as raw material for medicinal and industrial applications. However, due to limited research efforts to gather relevant information on breeding behaviour and inheritance of desirable traits of existing cultivars to enhance yield and nutritional contents, economic potential of the crop has not been fully exploited. The present study was therefore i...

Morphological And Genetic Characterisation Of Some Lima Bean (Phaseolus Lunatus L.) Cultivars And Their Nodulating Rhizobia

Abstract Three major investigations were carried out to assess the morphological traits and nodulation potential of thirteen lima bean cultivars as well as the genetic diversity of rhizobia nodulating these lima bean cultivars. Thirteen lima bean cultivars obtained from the CSIR-PGGRI and various market centres in Ghana were used. The experiment was conducted in pots filled with natural topsoil and arranged in a randomised complete block design (RCBD) with three replicates at the Biotec...

Characterization Of Yellow-, Red-, And Purple- Kernel Maize (Zea Mays L.) Accessions In Ghana.

AbstractTwenty yellow-, red- and purple-kernel maize accessions were collected from three regions in Ghana for the study. The objectives were to characterize the yellow-, red- and purple-kernel maize accessions in Ghana using phenotypic traits in order to determine their identity, using molecular traits for confirmation of their identity and to determine the presence of the opaque -2 gene and -carotene content of the grains as a way of assessing nutritional quality. A replicated field expe...

Effect Of Irradiation And Colchicine On Callus And Somatic Embryo Formation In Cassava (Manihot Esculenta Crantz)

ABSTRACTA study was conducted to assess the mutagenic effect of gamma radiation on sprouting and height in four local cassava accessions.The four cassava accessions were assessed for their callus induction and somatic embryo formation ability from leaf lobes from gamma irradiated stakes as well as colchicine treated leaf lobes on different concentrations of plant growth regulators, incorporated into Murashige and Skoog, (1962) (MS) basal medium. The cassava accessions were irradiated at 0, 32...

Yield, Quality and Nodulation Studies of Kersting’s Groundnut [Macrotyloma geocarpum, (Harms) Merachal and Baudet] in the Coastal Savannah AgroEcological Zone of Ghana

ABSTRACT Two investigations were carried out in the field and laboratory to assess variation in yield and nodulation potential as well as differences in the types of Rhizobia nodulating some local accessions of Kersting‟s groundnut (Macrotyloma geocarpum Harms) Marechal and Baudet in the Coastal Savannah Agro-Ecological Zone of Ghana. The aim was to obtain information relevant to important yield and nodulation attributes of Kersting‟s groundnut under prevailing agro-ecological condi...

Effect of NPK Fertilizer on Growth, Flowering And Yield of Fonio (Digitaria exilis) in a Coastal Agro-Ecological Environment of Ghana

ABSTRACT Fonio (Digitaria spp) is a neglected and underutilised crop traditionally grown in the Sahelian savannah agro-ecological zone of Ghana for its grain which is rich in crude protein, fibre and has medicinal properties. Decline in production of the crop is attributed to poor agronomic and yield characteristics and changing agro-climatic conditions as a result of global warming which has rendered traditional growing areas too dry to support cultivation of the crop. There is a need ...

Propagation And Molecular Characterisation Of Rubber Tree (Hevea Brasiliensis Muell. Arg.) In Ghana

ABSTRACT The study was aimed at the propagation and molecular characterisation of some introduced clones of Hevea brasiliensis in Ghana. Propagation of H. brasiliensis by stem cuttings and in vitro techniques was used to study alternative procedures for mass production of rubber planting materials. Brown and green stem cuttings of Clone I and Clone II were soaked for 6 hours in 0.0-22.5g/L NAA followed by propagation in a nursery bag filled with nutrient-rich soil. Only the brown s...
