Molecular markers for and quality assessment of near isogenic palmiet and SST66 wheat lines for Pmeudocercosporella herpotrichoides (eyespot) resistance
(University of the Free State, 2000-11)
English: 1. The aim of this study was to determine whether the presence of the Pch 1
gene, has an effect on breadmaking quality and yield in two genetic
backgrounds, to find a molecular marker linked to the gene, using ...
Isolation and characterization of a possible polygalacturonase: inhibiting protein from wheat
(University of the Free State, 2001)
English: The presence and possible role of polygalacturonase-inhibiting protein (PGIP) in
wheat (Triticum aestivum) as part of the plant's defense reaction following leaf rust
(Puccinia triticina) infection were ...
The improvement of leaf rust resistance in selected bread wheat lines
(University of the Free State, 2002-11)
English: The objective of this study was not only to improve leaf rust (caused by
Puccinia triticina) resistance in selected wheats (Triticum aestivum L.), but to
focus on durability as well as agronomic acceptability ...
A comparison of monosomic and disomic substitution lines in the chromosomal location of leaf rust resistance genes in tetraploid wheats
(University of the Free State, 2003-05)
English: Two sets of aneuploids were employed and compared to localize adult plant
leaf rust resistance genes in tetraploid wheat accessions. One set was the
hexaploid Chinese Spring (CS) A- and B-genome monosomics ...
Host-pathogen studies of wheat leaf rust resistance in Triticum turgidum
(University of the Free State, 2003-05)
English: Wheat and the wheat leaf rust pathogen Puccinia tritieina co-evolved for several
millennia. The frequency by which host resistance genes are overcome by the
pathogen has lead to a constant search for new genes, ...
Wheat leaf rust resistance in selected Triticum turgidum accessions
(University of the Free State, 2002-05)
English: In wheat, the depletion of genes for rust resistance necessitates the search for
alternative sources of diversity. Species related to wheat, e.g. Triticum turgidum,
provide such a source of new and hopefully ...
Combining wheat rust and fusarium head blight resistance genes and QTL using marker-assisted selection
(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 ...
Aspects of ß-1,3-glucanase expression in wheat associated with Russian wheat aphid resistance
(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 ...
Targeting quantitative trait loci for adult plant stripe rust resistance in wheat
(University of the Free State, 2007-11)
English: Stripe rust, caused by Puccinia striiformis West. f. sp. tritici is one of the most damaging
diseases of wheat (Triticum aestivum L.) globally. The South African wheat cultivar Kariega
expresses APR and has ...
Genetic variability for Russian wheat aphid, Diuraphis noxia resistance in South African wheat genotypes
(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 ...
