Technical Abstract: The Colorado Agricultural Experiment Station announces the release of ‘Croissant’, disease-resistant pinto bean (Phaseolus vulgaris L.) variety. Croissant was developed at Colorado State University and tested in the Western Regional Bean Trials, Midwest Regional Performance Nursery, and Colorado Crop Testing Program as CO23704. Croissant was derived from a single F5 plant selection in 2001 from the pedigree BelDakMi-RR-3/CO07010-2//WM2-93-5. BelDakMiRR-3 is a pinto line released by the USDA-ARS for resistance to rust; CO07010-2, is a pinto line from the Colorado State University Breeding Project that has semi-upright architecture, resistance to rust caused by Uromyces appendiculatus, and excellent pinto seed quality; and WM2-93-5 is an experimental pinto line from Dr. Dermot Coyne, University of Nebraska Dry Bean Breeding Project. WM2-93-5 possesses resistance to rust, field tolerance to common bacterial blight caused by Xanthomonas campestris pv. phaseoli and has semi-upright architecture. Hybridization of parental lines was made at the Colorado State University greenhouse, Fort Collins, CO. The line was selected at the Agricultural Research, Demonstration, and Education Center, Fort Collins, and pure seed was increased at the Western Colorado Research Center, Fruita, Colorado. Foundation seed of Croissant will be released to seed producers in May 2008. Application for Foundation Seed can be made to Mr. Fred Judson, Western Colorado Research Center, 3168 B 1/2 Road, Grand Junction, Colorado 81503-9621. Plant Variety Protection under Title V will be sought. A “Technology Fee” paid to the Certification agency in the state of production will be assessed on all Registered and Certified seed produced. Seed for testing is available from Mark Brick, Department of Soil and Crop Sciences, Colorado State University, Fort Collins, CO 80523, 970-491-6551 or Mark.Brick@Colostate.edu.
