BGS 590, Reaction to Puccinia hordei 13 (barley leaf rust), Rph13
Stock number: BGS 590
Locus name: Reaction to Puccinia hordei 13 (barley leaf rust)
Locus symbol: Rph13
Previous nomenclature and gene symbolization:
Monofactorial dominant (2, 3).
Location is unknown (2).
The seedling reaction to most isolates of Puccinia hordei is a small necrotic fleck (2). The seedling reaction of heterozygotes is indistinguishable from that of homozygous resistant seedlings (2).
Origin of mutant:
Observed in line BS 99-2-1 (PI 531849) from the Cambridge Plant Breeding Institute (2, 3), which was selected from a cross having a Hordeum vulgare subsp. spontaneum accession from Israel as the donor parent (3).
Rph13.x in Hordeum vulgare subsp. spontaneum (HS 2986) and transferred to Berac (PI 355136) by backcrossing [BS 99-2-1 (Berac*3/HS 2986), PI 531849, GSHO 1591] (1, 2, 3).
Mutant used for description and seed stocks:
Rph13.x from HS 2986 in Berac (PI 355136)*3 (PI 531849, GSHO 1591); Rph13.x in Bowman (PI 483237)*3 (GSHO 2325); Rph13.x in Bowman*7 (PI 643162, BW685, NGB 22391).
