'Duster' wheat: A durable, dual-purpose cultivar adapted to the southern great plains of the USA. Journal of Plant Registrations. 6(1):1-12.
Interpretive Summary: A new wheat cultivar ‘Duster’ has been developed. Since its release in 2006, Duster has gained broad acceptance in the US southern Great Plains region with a definitive grain yield advantage and added dough strength. Other important agronomic traits of Duster include aluminum tolerance; effective levels of resistance to diseases including soilborne mosaic, spindle streak mosaic, leaf rust, and stem rust; and high levels of seedling resistance to Hessian fly biotype GP. Duster is susceptible to Fusarium head blight. Duster was selected from a double cross, W0405/NE78488//W7469C/TX81V6187, made in 1987 within the former HRW wheat breeding program of Pioneer Hi-Bred International, Inc. Neither Duster nor its immediate parents are known to have a sib-pair or parent-offspring relationship with cultivars currently in production in the Great Plains.
Technical Abstract: Winter wheat (Triticum aestivum L.) cultivars which gain broad commercial acceptance in Oklahoma and surrounding states of the U.S. southern Great Plains must produce a definitive grain yield advantage, and they must demonstrate season-long dependability in dual purpose management systems, effective resistance to multiple viral and fungal diseases, and in lower-elevation areas tolerance to soil acidity. Our objective was to corroborate each of those strengths in the hard red winter (HRW) wheat cultivar ‘Duster’ (Reg. XX, PI 644016), released in 2006 by the Oklahoma Agricultural Experiment Station and the USDA-ARS to complement ‘Endurance’ (Reg. No. CV-994, PI 639233) with added dough strength and resistance to Wheat spindle streak mosaic virus. Duster was selected from a double cross, W0405/NE78488//W7469C/TX81V6187, made presumably in 1987 within the former HRW wheat breeding program of Pioneer Hi-Bred International, Inc. Neither Duster nor its immediate parents are known to have a sib-pair or parent-offspring relationship with cultivars currently in production in the Great Plains. Duster is a descendent of a F2:3 line identified in Oklahoma in 1991, from which pedigree selection produced two F13-derived lines that were eventually composited to constitute breeder seed. Experimental line OK93P656H3299-2C04 was tested in the 2005 and 2006 Southern Regional Performance Nursery, where it ranked first and fifth, respectively, for mean grain yield. Data from the Oklahoma Small Grains Variety Performance Tests was primarily used herein to demonstrate continued competiveness for grain yield, forage biomass, and allied traits in a wide array of environmental conditions, five years following Duster’s release.
