BGS 267, Reaction to Puccinia hordei 11 (barley leaf rust), Rph11
Stock number: BGS 267
Locus name: Reaction to Puccinia hordei 11 (barley leaf rust)
Locus symbol: Rph11
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial dominant (1).
Located in chromosome 6HL (1); Rph11.p is about 7.0 cM proximal from the Acp3 (Acid phosphatase 3) locus; Rph11.p is about 11.0 cM proximal from the Dip2 (Dipeptidase 2) locus (1).
Description:
The seedling reaction varies from a necrotic fleck to a moderate sized uredinium with heterozygotes having an intermediate reaction (1). Culture Aust 220 from Australia is required to detect a resistant reaction in allelism tests and backcrosses. Seedlings tend to show a moderate sized uredinium as a reaction to many isolates of Puccinia hordei.

Origin of mutant:
Natural occurrence in accession 'Maalot 17' of Hordeum vulgare subsp. spontaneum, but isolated as a Clipper backcross-derived line containing one of two Rph genes in the original accession (1).
Mutational events:
Rph11.p (BC67, GSHO 1589) from Hordeum vulgare subsp. spontaneum in Clipper*4/Maalot 17 (1).
Mutant used for description and seed stocks:
Rph11.p (BC67, GSHO 1589) in Clipper*4/Maalot 17; Rph11.p in Bowman (PI 483237)*2 (GSHO 2092); Rph11.p in Bowman*6 (PI 643160, BW684, NGB 22390).
