Comment:
Some plants of Altgold Rotkorn possess Lr71 conferring IT 12C {10848}.
Comment:
One of two complementary genes; the second gene, Lr31, is located in chromosome 4BS {1367}. The following wheats have both Lr27 and Lr31. Lr27 is present in wheats with Sr2, but is not expressed in the absence of the complementary factor {1366}.

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}.
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}.

Lr48 is closely linked with Lr25 {10738}. Based on haplotype analysis Lr48 was postulated in 13 Australian Condor relatives {11112}. The suggestion that this gene is present in 13 Australian varieties carrying Lr48 markers and hence Lr48 {11172} needs verification.

Comment:
In addition to conferring seedling and adult plant resistance, Lr34 responds in a complementary manner when combined with either Lr33 or LrT3 {321}. In the Thatcher background, Lr34 is associated with increased resistance to stem rust {299,321}. Although the resistance gene in the near-isogenic Thatcher line, RL6077, was considered to be Lr34 on the basis of disease response, leaf tip necrosis and its association with resistance to stripe rust, a cross with RL6058 segregated for two genes. A translocation to another chromosome was suggested {324}.
A QTL, which is likely to correspond to Lr34, was identified in the Opata 85/W-7984 (ITMI) RI mapping population. The resistance was contributed by Opata 85 {0090}. On the basis of leaf tip necrosis and lack of segregation in a diallel, cv. Saar, Simogh, Homa, Parastoo and Cocnoos were considered to have Lr34, but each also possessed 2 or 3 additional adult plant resistance factors {10110}. This gene is identical to Yr18, Pm38 and Ltn and confers stem rust resistance in some genetic backgrounds. Diagnostic markers based on the gene sequence are reported in {10713}; AC Domain, Cappelle Desprez, H-45, Jagger, Newton, RL 6077, and H-45 do not carry Lr34 {10713}.

Lr19 is usually associated with Sr25. Sears' transfer 7D-7Ag No. 11 carries neither Lr19 nor Sr25. See Lr29. Knott {681} obtained two mutants (28 and 235) of Agatha possessing Lr19, but with reduced levels of yellow pigment in the flour. Marais {890,892} obtained mutants and recombined lines with intermediate levels of, or no, yellow pigment. It was shown that recombinant line 88M22-149 lacked yellow pigment {1163}. Secondary translocation line I-96 derived from Sears' 7D-7Ag no.1 involved Lr19 being located in an intercalary segment with low yellow pigment and lacking Sd1 {10255}. Lr19 in lines I-22 and I-23 retaining yellow pigment but lacking Sd1 was transferred to durum chromosome 7BL {10255}. One of the lines with the shortest 7Ag segment, Lr19-I49-299, was used in a further cycle of recombination {10278}.

A resistance gene analog containing an NBS-LRR R gene sequence was isolated from the Ae. ventricosa segment carrying Lr37 {0183}. The 2NS translocated segment carrying Lr37 replaced the distal half of chromosome 2A (25-38 cM) from Xcmwg682-2A to XksuH-9-2A. PCR markers were developed for the 2NS and 2AS alleles of Xcmwg682{10073}. SCAR markers SC-372 and SC-385 were developed in {10796}.

Comment:
The Lr14 region in tetraploid wheat harbours Qlr.ubo-7B.2, a gene that confers durable resistance in durums {10734, 10736} and that is present in many Italian, CIMMYT and ICARDA durum cultivars {10736}. The relationship of this gene described as Lr14c (reference genotype Creso) in {10735} remains to be determined. Reasons for considering Lr14c as a unique allele are given in {10735}. In association mapping the presence of QLr.ubo-7B.2 was predicted with 96% accuracy based on appropriate alleles of Xcfa2257.2, Xgwm344.2 and Xwmc10 in the distal region of chromosome 7BL {10736}.
