Patterns of heterosis in crosses between African stalk borer resistant and elite maize genotypes
(University of the Free State, 2008-11)
English: Since conventional sources of resistance to stem borers are not adapted to South African conditions, resistance has to be introgressed into locally adapted breeding material. Combining ability for resistance ...
Assessment of genetic diversity, combining ability, stability and farmer preference of cassava germplasm in Ghana
(University of the Free State, 2012-11-11)
English: The aim of this study was to assess genetic diversity, combining ability, heterosis, heritability of
traits, stability and farmer preference of cassava germplasm in Ghana in order to structure an
effective ...
Mycotoxigenic fungi associated with ear-rots in Zimbabwe: identification and inheritance of resistance in southern and West African maize inbred lines
(University of the Free State, 2015-06)
English: Fumonisin, a mycotoxin produced by Fusarium verticillioides, is an intrinsic constraint in maize (Zea mays L.) that has received a low level of attention in Zimbabwe, despite existence of laws nationally and ...
Breeding potential of cassava (Manihot esculenta Crantz) in Mozambique
(University of the Free State, 2008-05)
English: This study represents the first comprehensive genetic study based on local cultivars of Mozambique. Five cassava (Manihot esculenta Crantz) parents were crossed in a full diallel. The parents and F1 progeny were ...
Diallel and stability analysis of kenaf (Hibiscus cannabinus L.) in South Africa
(University of the Free State, 2005-11)
English: Kenaf (Hibiscus cannabinus L.) is an important fiber crop world wide, and has a great potential for its multipurpose uses. It could play a significant role in future fiber supply in Southern Africa. Six diverse ...
Improvement strategies for yield potential, disease resistance and drought tolerance of Zimbabwean maize inbred lines
(University of the Free State, 2012-06)
English: Breeding for drought and low N tolerant genotypes in Zimbabwe is an important intervention that will see the country curbing the food in-security problem. Both CIMMYT and DR&SS maize germplasm was used in this ...
Studies on genetic variability, inheritance and heterosis in pepper (Capsicum annuum L.)
(University of the Free State, 2003-11)
English: The knowledge of genetic similarity and dissimilarity among crop cultivars is of vital
importance for the plant breeder. The genetic variability of 39 pepper (Capsicum annuum
L.) genotypes of different varietal ...
