Evaluation location: Montana, United States
One thousand safflower accessions obtained from the USDA/ARS Western Regional Plant Introduction Center were planted May 11, 1993 at the MSU Eastern Agricultural Research Center, Sidney, MT. The accessions were planted in 20 ft rows at a dry land fallow site with check varieties every 20th row for comparative purposes. Data was collected on the following safflower field descriptors:rosette period, head diameter, Pseudomonas bacterial blight disease rating, location and angle of branches, internode length, outer involucral bract descriptors, and bloom date. Due to unusual and record setting cool temperatures and precipitation amounts received during the growing season and an early fall killing frost most seed of the accessions failed to mature and prevented meaningful oilseed laboratory analyses of oil and meal quality characteristics of the accessions.
