Agro-morphological and genetic characterization of advanced potato (Solanum tuberosum L.) breeding lines in Mahikeng, South Africa
(North-West University (South Africa), 2022)One of the most important strategies for increasing crop productivity and improvement in potato yield output is the development and introduction of new cultivars. Phenotypic characteristics are the first aspects to consider ... -
Amphibian diversity and breeding behaviour in the Okavango Delta
(North-West University, 2010)Amphibians are of great ecological importance and a loss of species will have widespread and dire consequences. Recent population declines and extinctions have resulted in amphibians being labelled the most threatened ... -
Determining the economic significance of the lion industry in the private wildlife tourism sector
(North-West University (South Africa) , Potchefstroom Campus, 2016)Since little reliable data or statistics are available regarding the management of lions in the private sector and their economic significance in the private wildlife industry, the research was undertaken to determine the ... -
Host plant resistance as a management tool for Ditylenchus africanus (Nematoda : Tylenchidae) on groundnut (Arachis hypogaea)
(North-West University, 2008)Groundnut is an important cash crop both for commercial and smallscale farmers in South Africa. The effect of Ditylenchus africanus on groundnut is mainly qualitative, leading to downgrading of groundnut consignments. This ... -
Host response of rice genotypes from crosses of high-yielding and drought-tolerant Oryza sativa advanced breeding lines to the rice root-knot nematode Meloidogyne graminicola
(Taylor & Francis, 2018)The host response to Meloidogyne graminicola infection of 30 advanced breeding lines developed from crosses between high-yielding and drought-tolerant Oryza sativa genotypes was evaluated in outdoor raised beds. None of ... -
Mapping quantitative trait loci of Meloidogyne graminicola resistance and tolerance in a recombinant inbred line population of Oryza glaberrima × O. sativa
(Brill, 2019)Host response of BC2F3 recombinant inbred line (RIL) population derived from a cross between African rice (CG14) and Asian rice (IR64) genotypes was evaluated in the field and quantitative trait loci (QTLs) that confer ... -
QTL mapping for resistance to and tolerance for the rice root-knot nematode, Meloidogyne graminicola
(BioMed Central, 2018)Background The root-knot nematode Meloidogyne graminicola is an obligate biotrophic pathogen considered to be the most damaging nematode species that causes significant yield losses to upland and rainfed lowland rice ... -
The role of plant breeders' rights in an evolving peach and nectarine fresh fruit sector
(Academy of Science of South Africa (ASSAf), 2017)The evolving impact of plant breeders' rights was investigated in a bid to provide a basis for understanding the complex relationship that exists between scientific, legislative and market matters that shape the peach and ...
