Gene Symbol detail

Gene Symbold
Class Level 1 Reaction to Puccinia triticina
Level 2 Genes for resistance
Level 3
Level 4
Symbol Wild Type Lr18
Allele
Symbol comment Derived from T. timopheevii. Independently derived lines with Lr18 possess a unique N band terminally located in chromosome 5BL {1614}. Low seedling responses conferred by Lr18 are most effective at 15-18C. With increasing temperatures the response becomes less effective and ineffective at 25-27C {935,see also,1614}.
Chromosomes 5BL {935} = T5BS.5BL-5G#1L{389}

Comment A resistance gene, LrTt2, in line 842-2 was located on chromosome 5BL in a similar region to Lr18. The claim that Lr18 and LrTt2 were different based on low seedling infection types, but the genetic background were different {10752}.
