Journal ArticleDOI
AFLP and STS tagging of Lr19, a gene conferring resistance to leaf rust in wheat
TL;DR: The conversion process of AFLP fragments to STS markers was technically difficult, mainly because of the presence of contaminating fragments, but a general verification strategy was formed prior to clone sequencing to reduce the frequency of false positives and to identify the correct clone.
Journal ArticleDOI
Leaf rust and stripe rust resistance genes transferred to common wheat from Triticum dicoccoides
TL;DR: Linked leaf rust and stripe rust resistance genes introduced from Triticum dicoccoides protected common wheat seedlings against a range of pathotypes of the respective pathogens.
Journal ArticleDOI
Intergeneric transfer (rye to wheat) of a gene(s) for Russian wheat aphid resistance
G. F. Marais,M. Horn,F. Du Torr +2 more
TL;DR: An octoploid triticale was derived from the F 1 of a Russian wheat aphid-resistant rye and recovered five euploid Russian-wheat-aphid- resistant plants.
Journal ArticleDOI
Leaf rust and stripe rust resistance genes Lr54 and Yr37 transferred to wheat from Aegilops kotschyi
TL;DR: The tendency of unpaired meiotic chromosomes to undergo centric misdivision was exploited to translocate leaf rust and stripe rust resistance genes from an Aegilops kotschyi addition chromosome to a group 2 chromosome of wheat.
Journal ArticleDOI
Leaf Rust and Stripe Rust Resistance Genes Derived from Aegilops Sharonensis
TL;DR: Linked leaf and stripe rust resistance genes introgressed into hexaploid wheat from Aegilops sharonensis provided protection in the seedling stage to a wide range of pathotypes of the two diseases.
