Narrative
Ruby Lee was produced by a modified bulk-breeding method, followed by pedigree selection, and was derived from a single plant in the F9 generation, and tested as experimental line OK05526-RHf. Ruby Lee is closely related to the HRW cultivar, Endurance, since Endurance is a reselection from the line OK94P549. Ruby Lee is widely adapted to the southern and central Plains, and the southern High Plains. It exhibits a semi-erect growth habit during the vegetative period. Regarding reproductive developmental patterns, Ruby Lee has alleles VRN-A1b (delayed initiation of stem elongation), PPD-D1b (photoperiod insensitivity), and VRN-D3a allele (accelerated physiological maturity), based on the respective gene markers. Ruby Lee is moderately susceptible to acidic soil conditions. Its high level of cold tolerance in the vegetative stages is similar to Endurance. Ruby Lee is 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 carries gene Lr39/41 conferring resistance to leaf rust caused by Puccinia triticina, but other unknown genes must be present to produce a moderately resistant reaction to races present in Oklahoma in the field. Ruby Lee also exhibits an intermediate to moderately resistant adult plant reaction to naturally occurring races of stripe rust (caused by Puccinia striiformis f. sp. tritici) in the field in Oklahoma, but under Kansas field conditions of induced and elevated pressure from stripe rust race PST100, it shows a moderately susceptible reaction. Based on combined greenhouse and field observations, Ruby Lee is resistant to tan spot (Pyrenophora tritici-repentis) but shows an susceptible reaction to septoria leaf blotch (Septoria tritici) and an intermediate adult-plant reaction to powdery mildew (Blumeria graminis f. sp. tritici). Wheat protein content of Ruby Lee is considered moderately high for most HRW cultivars (12.8%, 5-yr average, Oklahoma). Kernel size is large (2.64 mm kernel diameter and 34 mg kernel weight; 5-yr average, Oklahoma). Test weight and baking quality attributes are generally excellent. Ruby Lee possesses high-molecular weight (HMW) subunits 2*, 7*+8, 2+12 (A, B, and D Glu-1 loci, respectively). It does not contain either the T1BL-1RS or T1AL-1RS translocation.
