Genetic studies revealed a recessive gene, designated rpg4, that confers resistance to pathotypes QCC and MCC at low incubation temperatures (18-23C). Also posses genes for resistance to leaf rust and powdery mildew.1483028PI 584766

10GSHO 2438rpg4.dHordeum vulgare L. subsp. vulgare North Dakota, United StatesNSGCKERNELS1996DONATED04/1996Genetic materialThe rpg4.d gene confers low infection types to pathotypes QCC and MCC of the wheat stem rust pathogen (Puccinia graminis f sp tritici) at the seedling stage under low incubation temperatures 18 to 22 degrees C. This gene is ineffective (exhibits compatible infection types) against some pathotypes at incubation temperatures greater than 27 degrees C. At the adult plant stage, the rpg4.d allele confers a moderate to high level of resistance to pathotype QCC. The rpg4.d gene confers a dominant resistant reaction to Puccinia graminis f sp secalis. Inheritance: Monofactorial recessive. Located in chromosome 5HL [7L], in central part of 5HL about 4.9 cM distal from RFLP marker MWG740. Previous nomenclature and gene symbolization: None. Mutational events: rpg4.d in Q21861. Mutant used for description and seed stocks: rpg4.d in Q21861 (GSHO 2438).1545054GSHO 2438
