Interpretive Summary: Diseases are one of the main factors reducing seed yield in the Unites States. Among these, the bean rust disease, which is caused by a pathogen that is continuously producing new virulent strains, is recurrent in North Dakota, the largest producer of dry beans in the United States. About 50% of the US production is pinto beans. A new race of the bean rust pathogen was identified in 2008 in North Dakota that was virulent on common bean varieties. Collaborative studies between North Dakota State University and ARS-Beltsville showed that resistance genes such as Ur-5 and Ur-11 were effective against this new race. Hence, the dry edible bean breeding program at NDSU increased efforts towards incorporating these genes within their dry bean breeding pipeline. NDSU and ARS-Beltsville report a new pinto bean cultivar, named ND Falcon, with resistance to all known virulent strains of the rust pathogen in the United States. ND Falcon is also resistant to the soybean cyst nematode, a new disease of common bean in North Dakota. ND Falcon has excellent upright architecture needed for direct harvest and seed yield like other popular pinto varieties grown in North Dakota. Given the many positive attributes of ND Falcon, including disease resistance, it is anticipated that it this new pinto bean cultivar will be of interest to pinto bean growers and will help protect common bean production in the US.

Technical Abstract: ND Falcon pinto bean (PVP-201900174, Reg. No. _____, PI ____) is a new cultivar developed by the dry bean breeding program at North Dakota State University (NDSU), and released by the North Dakota Agricultural Experiment Station (NDAES). In terms of area and consumption, pinto bean is the most important market class in the United States. North Dakota is the largest producer of dry beans in the country and ~50% of its production is pinto beans. However, biotic and abiotic stresses are the main factors for seed yield reductions. Between 2013 and 2018, ND Falcon was tested across more than 22 environments in North Dakota along with pinto cultivars commonly grown in the region. Averaged across environments, seed yield of ND Falcon was not significantly different from commonly grown pinto bean cultivars in the region. Nonetheless, ND Falcon is resistant to the most common race of bean rust (20-3) and to Soybean Cyst Nematode (HG Type 0). Therefore, we would expect a seed yield advantage to ND Falcon under disease pressure compared to other pinto bean cultivars commercially available in North Dakota. In addition, growers could reduce production costs by eliminating/reducing fungicide and nematicide applications. ND Falcon has white flowers and the seed of ND Falcon is of the appropriate shape and color for the pinto market class. ND Falcon has excellent upright architecture (type IIa) with short vines. Under North Dakota conditions, ND Falcon shows an average plant height of 53 cm, seed size of 37.0 g per 100 seeds, and matures in approximately 103 days. Other traits of agronomic/economic importance are within acceptable commercial ranges for pinto beans.
