    Grain yield and breadmaking quality of wheat lines with leaf rust resistance genes Lr29, Lr34, Lr35, and Lr37 

    Grobbelaar, Benida (University of the Free State, 1999-06)
    English: 1. The aim of this study was to determine if the leaf rust resistance genes Lr2g, Lr34, Lr35 and Lr37 have an effect on the quality and yield characteristics of a cultivar it is incorporated into. 2. Near-isogenic ...

    Genetic variability for Russian wheat aphid, Diuraphis noxia resistance in South African wheat genotypes 

    Tolmay, Vicki Louise (University of the Free State, 2006-07)
    Near-isogenic genotypes 1684/Tugela and 2199/Tugela containing D. noxia resistance ex SA1684 [PI 137739 (Dn1)] and SA 2199 [PI 262660 (Dn2)] were studied in terms of antibiosis, antixenosis and tolerance, population ...

    Biochemistry of Russian wheat aphid resistance in wheat: involvement of lipid-like products 

    Berner, Jacques (University of the Free State, 2007-11-03)
    Physical damage and disease are known to cause changes in the lipid composition of plants. The biochemical pathways that lead to changes in the lipid composition were investigated in a comparative study using Russian wheat ...

    Molecular and biochemical characterisation of rust and Fusarium head blight resistant wheat lines 

    Du Plessis, Ansori (University of the Free State, 2013-06)
    English: Wheat is one of the most important food crops and consumption in the past year was higher than production worldwide, which indicates improved wheat cultivars need to be developed to maintain the demand for wheat. ...

    Characterization of some early defence responses of leaf rust-infected wheat 

    Appelgryn, Johannes Jacobus (University of the Free State, 2007)
    The aim of this study was to investigate the early events following the infection of wheat with leaf rust. An attempt was made to identify and characterize genes putatively involved in these early events. More specifically, ...

    Combining wheat rust and fusarium head blight resistance genes and QTL using marker-assisted selection 

    Senoko, Katleho Joyce (University of the Free State, 2014-01)
    English: Wheat (Triticum aestivum) is one of the most important cereal crops worldwide and cultivated in a wide range of environments. The production of wheat, based on consumption and other demands, needs to be increased ...

    Cloning of genes involved in the early response of wheat towards Russian wheat aphid infestation 

    Huang, Ju-Chi (University of the Free State, 2004)
    English: The interaction between wheat (Triticum aestivum) and the Russian wheat aphid (Diuraphis noxia) was investigated on a molecular level. The resistant cultivar, Tugela DN1, was infested with the Russian wheat ...
    Thumbnail

    The influence of environment on the expression of Russian wheat aphid; Diuraphis noxia (Kurdjumov) resistance 

    Lindeque, Robert Crowther (University of the Free State, 2008-05)
    English: The purpose of this study was to investigate the effect of variations in climatic factors such as vernalization periods, minimum- and maximum temperatures and rainfall on the expression of host plant resistance ...

    Metabolic aspects of the early response of leaf rust-infected wheat 

    Huang, Ju-Chi (University of the Free State, 2008)
    English: The aim of this study was to study various aspects of the defence response of wheat infected by Puccinia triticina. SSH was used to isolate differentially expressed cDNA fragments from P. triticina infected wheat. ...

    Aspects of ß-1,3-glucanase expression in wheat associated with Russian wheat aphid resistance 

    Wilding, Willem Jacobus Marthinus (University of the Free State, 2003-11)
    The aim of the study was to learn more about the expression of b-1,3-glucanase during the resistance response of wheat to the RWA (Diuraphis noxia)(Mordvilko). The different resistance genes (Dn1, Dn2 and Dn5) used in the ...
