The South African Germplasm Collection of Groundnut, Arachis hypogaea L., and its utility
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A.J. Cilliers --- , Republic of South Africa C.J. Swanevelder --- , Republic of South AfricaGroundnut is an important crop for both the commercial and developing farmer in South Africa, providing a source of plant protein and oil. Commercial production varies from 80 000 to 200 000 tons per annum. The only research institute in... -
Recurrent selection for resistance in maize to the African stalk borer, Busseola fusca (Fuller)
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: J. B.J. van Rensburg --- , South Africa J. Klopper --- , South AfricaStem borer resistant inbred lines Mp704 and Mp706 of Mississippi origin were used as donor parents in a recurrent selection programme, to develop locally adapted germplasm with improved resistance to the stalk borer Busseola fusca. The segregating progenies of crosses... -
Assessment of genetic diversity of rice based on SNP markers for selection of parents for sheath rot (Sarocladium oryzae) resistance breeding
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Simon M Mvuyekure --- African Centre for Crop Improvement, School of Agricultural, Earth and Environmental Sciences, South Africa Julia Sibiya --- African Centre for Crop Improvement, School of Agricultural, Earth and Environmental Sciences, South Africa John Derera --- African Centre for Crop Improvement, School of Agricultural, Earth and Environmental Sciences, South Africa John Nzungize --- Rwanda Agriculture Board, Rwanda Germain Nkima --- Rwanda Agriculture Board, RwandaSheath rot of rice, caused by Sarocladium oryzae, is an important emerging rice disease not only in Rwanda, but also in other rice-growing countries. Given that cultivar resistance is a sustainable management strategy for small-scale farmers, the aim of this... -
Detection of rust resistance in selected Zimbabwean and ICARDA bread wheat (Triticum aestivum) germplasm using conventional and molecular techniques
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Bruce Mutari --- Crop Breeding Institute, Zimbabwe Sripada M Udupa --- Biotechnology Section, International Center for Agricultural Research in the Dry Areas (ICARDA), Morocco Peter Mavindidze --- Department of Agronomy, South Africa Charles S Mutengwa --- Department of Agronomy, South AfricaHost resistance is the most effective and economical method to minimise yield losses caused by rusts. The aim of this study was to detect the presence of resistance in 75 wheat genotypes. The presence of the genes Sr2, Sr24, Lr34,...
