Variation of oil content and fatty acid composition in selected lines of vernonia (Vernonia galamensis variety ethiopica)
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: H.A. Shimelis --- Department of Plant Sciences, M.T. Labuschagne --- Department of Plant Sciences, A. Hugo --- Department of Microbial, Biochemical and Food Biotechnology,Vernonia (Vernonia galamensis) is a new industrial crop that could offer a naturally epoxidized oil with great economic value. The oil content and fatty acid composition of 10 selected lines of V. galamensis variety ethiopica were analysed to study the... -
Principal agronomic and seed oil traits in the industrial oil crop vernonia (Centrapalus pauciflorus var. ethiopica)
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Hussein A Shimelis --- School of Agricultural, Environmental and Earth Sciences, African Centre for Crop Improvement, South Africa Phatu W Mashela --- Department of Soil Science, Plant Production and Agricultural Engineering, South Africa Arno Hugo --- Department of Microbial, Biochemical and Food Biotechnology, South AfricaVernonia (Centrapalus pauciflorus) is potentially a new crop that could offer naturally epoxidised industrial oil. The objective of this study was to apply principal component analyses on agronomic traits, seed oil and fatty acid compositions in vernonia to identify the... -
Determination of optimum ethylmethanesulfonate conditions for chemical mutagenesis of selected vernonia (Centrapalus pauciflorus) accessions
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Sandile T Hadebe --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South Africa Albert T Modi --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South Africa Hussein A Shimelis --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South AfricaChemical mutagenesis could potentially increase allelic diversity and address genetic erosion in vernonia (Centrapalus pauciflorus) breeding programmes. The objective of this study was to determine an optimum treatment combination, i.e. exposure duration, temperature and ethylmethanesulfonate (EMS) dose that would reduce... -
Seed oil content and fatty acid composition response to ethyl methanesulphonate mutagenesis in vernonia
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Sandile Hadebe --- Department of Agronomy, Faculty of Science and Agriculture, South Africa Albert T Modi --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South Africa Arno Hugo --- Department of Microbial, Biochemical and Food Biotechnology, South Africa Hussein A Shimelis --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South AfricaVernonia [Centrapalus pauciflorus (Willd.) H.Rob.] is a novel industrial oilseed crop that can be used to produce vernolic acid, a naturally epoxidised fatty acid. The study objective was to determine whether ethyl methylsulphonate (EMS) mutagenesis significantly altered seed oil content...
