| # PI 632635 @ USDA-ARS (USA) INFO > GRIS | GRIS{Lr3, Lr24; Rht8a, Rht8c; Rht-B1b, Rht-D1a; no-1RS; Glu-A1b, Glu-B1w, Glu-D1d; Glu-A3c, Glu-B3g, Glu-D3a; Sr24, Sr1RSAmigo} | United States, Oklahoma (developed) | other # = GRIS{PI-632635} | Remark: Maturity intermediate, heading on the same day as 2174, 2 d later than Ok101 and 2.4 earlier than 2137. Semidwarf but shorter than most HRW cvs. currently in production, height at 77 cm is 8 cm shorter than 2174 and Ok101. Flag leaves at boot stage blue-green, erect, and twisted. Spikes middense, tapering, awned, white-glumed, and inclined to nodding at harvest-maturity. Juvenile plants semi-erect and show moderately late dormancy release during the late winter (similar to 2174 but later than Ok101 and Jagger). When measured at 15C in a growth chamber, coleoptile length (8.7 cm) is 2.1 cm longer than OK101, 0.4 cm longer than 2174, and 0.4 cm shorter than Jagger. Relatively high seed dormancy rating based on germination tests conducted at 4-12 wk post-harvest for seed stored at ambient temp. and germinated at 24/35C night/day temp. Seed dormany is not expressed at 13C constant temp. Based on the single kernel characterization system, means and standard deviation for kernel size and texture are 29.6 and 7.7 mg for kernel weight, 2.4 and 0.4 mm for kernel diameter, and 76 and 16 for kernel hardness. Resistant to soilborne mosaic virus, moderately susceptible to stem rust (Puccinia graminis), and resist. in adult-plant stages to Puccinia triticina, though seedling plants show susceptible reaction to races of leaf rust currently prevalent in the southern Great Plains. Postulated to have Lr3 and Lr24. Exhibits intermediate reaction to barley yellow dwarf virus in the field. Based on seedling tests in greenhouse, mod. resist. to tan spot (Pyrenophera tritici-repentis), and resist. to powdery mildew (Blumeria graminis). Insect reactions include a heterogeneous response to the Great Plains biotype of Hessian fly (Mayetiola destructor) and susceptibility to Russian wheat aphid (Diuraphia noxia) and to greenbug (Schizaphis graminum). Possesses no wheat-rye translocation. Grain protein levels average 135 g kg-1. Mixograph mixing time mod. high (6.0 mm and 5.1 on a 1-10 scale).
