Interpretive Summary: Bearpaw hard red winter (HRW) wheat was developed and released by the Montana Agricultural Experiment Station in September 2011. Bearpaw is of unknown pedigree, derived from a composite of five crosses made to the same F1 male sterile parent in 1999. Bearpaw was developed using a modified bulk-breeding method and selected as an F5:6 headrow. Bearpaw was tested under the experimental number MTS0721 from 2007 to 2011 in Montana. Quality has been evaluated in multilocation Montana trials since 2007. Bearpaw is a high-yielding, solid-stem, semidwarf HRW wheat cultivar with medium maturity, medium to high test weight and grain protein, and acceptable milling and baking quality. Bearpaw was released for its host-plant resistance to wheat stem sawfly conditioned by stem solidness, along with short stature and improved yield potential relative to existing solid-stem cultivars adapted to Montana.

Technical Abstract: ‘Bearpaw’ (Reg. No. CV-1083, PI 665228) hard red winter (HRW) wheat (Triticum aestivum L.) was developed and released by the Montana Agricultural Experiment Station in September 2011. Bearpaw is of unknown pedigree, derived from a composite of five crosses made to the same F1 male sterile parent in 1999: Dominant male sterile (DMS)/‘Rampart’//‘Pronghorn’/3/2*Rampart, DMS/Rampart//Pronghorn/3/Rampart/4/MTW9806, DMS/Rampart//Pronghorn/3/Rampart/4/‘Nuplains’,DMS/Rampart//Pronghorn/3/Rampart/4/MT9513, DMS/Rampart//Pronghorn/3/Rampart/4/MT98113. Bearpaw was developed using a modified bulk-breeding method and selected as an F5:6 headrow. Bearpaw was tested under the experimental number MTS0721 from 2007 to 2011 in Montana. Quality has been evaluated in multilocation Montana trials since 2007. Bearpaw is a high-yielding, solid-stem, semidwarf (Rht-B1b) HRW wheat cultivar with medium maturity, medium to high test weight and grain protein, and acceptable milling and baking quality. Bearpaw was released for its host-plant resistance to wheat stem sawfl y (Cephus cinctus Nort.) conditioned by stem solidness, along with short stature and improved yield potential relative to existing solid-stem cultivars adapted to Montana.
