Narrative
Garrison was produced by a modified bulk-breeding method, derived from a single plant in the F4 generation, and tested as experimental line OK05212. It bears no close resemblance, by pedigree, to other HRW cultivars currently in production. It is widely adapted to the southern and central Plains, and the southern High Plains. It exhibits an erect growth habit during the vegetative period. Regarding reproductive developmental patterns, Garrison has alleles VRN-A1b (delayed initiation of stem elongation), PPD-D1b (photoperiod insensitivity), and VRN-D3b allele (delayed physiological maturity), based on the respective gene markers. Garrison is highly tolerant of acidic soils but is negative for two SSR markers, Xwmc331 and Xgdm125, commonly used to screen for a major quantitative trait locus on chromosome 4DL associated with aluminum tolerance. Hence, Garrison must contain other gene(s) contributing to its greater level of aluminum tolerance and/or acid-soil tolerance. Garrison is highly resistant to Soilborne wheat mosaic virus and to Wheat spindle streak mosaic virus, moderately resistant to Wheat mosaic virus, and it exhibits good field tolerance to Barley yellow dwarf virus. It is moderately resistant to leaf rust (caused by Puccinia triticina) races present in Oklahoma, and it carries the Lr17 seedling resistance gene plus other unknown genes which produce a slow-rusting phenotype in the field. Presence of Lr34 is inconsistent and inconclusive based on PCR markers at three polymorphic sites of Lr34. Garrison also exhibits a highly resistant reaction in the adult plant to naturally occurring races of stripe rust (caused by Puccinia striiformis f. sp. tritici) in the field in Oklahoma, and under Kansas field conditions of induced and elevated pressure from stripe rust race PST100. Based on combined greenhouse and field observations, Garrison is resistant to tan spot (Pyrenophora tritici-repentis) but shows an intermediate reaction to septoria leaf blotch (Septoria tritici) and an intermediate to moderately resistant adult-plant reaction to powdery mildew (Blumeria graminis f. sp. tritici). Based solely on greenhouse tests, Garrison is moderately resistant to Fusarium head blight, caused by Fusarium graminearum Schwabe. Wheat protein content of Garrison is considered above-average for most HRW cultivars (12.6%, 5-yr average, Oklahoma). Kernel size is small (2.25 mm kernel diameter and 28 mg kernel weight; 5-yr average, Oklahoma). Test weight and baking quality attributes are generally very good. Garrison possesses high-molecular weight (HMW) subunits 1, 7*+8, 2+12 (A, B, and D Glu-1 loci, respectively). Garrison does not contain the T1BL-1RS or T1AL-1RS translocation.
