Registration of ‘Croissant’ Pinto Bean

Abstract

‘Croissant’ (Reg. No. CV‐299, PI 656597), a new medium‐maturity (92–98 d) pinto bean (Phaseolus vulgaris L.) cultivar was released by the Colorado Agricultural Experiment Station to provide dry bean producers in the USA with a high‐yielding cultivar that combines resistance to rust [caused by Uromyces appendiculatus (Pers.) Unger], most strains of Bean common mosaic virus (BCMV) and Bean common mosaic necrosis virus (BCMNV), and field resistance to common bacterial blight (CBB) [caused by Xanthomonas axonopodis pv. phaseoli (Smith) Vauterin et al.; Synonym: X. campestris pv. phaseoli Smith (Dye)]. Croissant has an indeterminant growth habit with semi‐upright plant architecture (Type IIb) in most environments; however, in environments with high soil N and moisture it can express semi‐vine architecture (Type IIIa). Resistance to rust is conditioned by the Ur‐3 (Middle American) and Ur‐6 (Andean) dominant alleles, and resistance to BCMV and BCMNV is conditioned by the recessive allele bc‐22. Croissant possesses the SAP6 marker linked with a quantitative trait locus (QTL) that confers a moderate level of field resistance to CBB endemic to the High Plains of the USA. In 2008 and 2009, the mean seed yield for Croissant was 3102 and 2895 kg ha−1 and the mean seed weights were 36.2 and 36.3 g/100 seed compared with 3142 and 3095 kg ha−1 and 38.2 and 37.7 g/100 seed for the mean of five test entries, respectively. Croissant is unique to other recent upright architecture pinto cultivars because it possesses two genes for resistance to rust and the SAP6‐linked QTL to provide a moderate level of resistance to CBB.

Postharvest seed coat darkening in pinto bean (Phaseolus vulgaris) is regulated by Psd, an allele of the basic helix‐loop‐helix transcription factor P

“…Seeds for pinto bean CDC Pintium and 1533‐15 were developed at the University of Saskatchewan, Canada. Seeds for the cultivars Sundance, StayBright, Croissant (Brick et al., 2011), Centennial, and DR Wood were obtained from Dr. Mark A, Brick, Colorado State University, USA; Lariat and ND‐Palomino were from Dr. Juan M. Osorno, North Dakota State University, USA (Osorno, 2010; Osorno et al., 2018) and Pinto Saltillo (Sanchez‐Valdez, Acosta‐Gallegos, Ibarra‐Pérez, Rosales‐Serna, & Singh, 2004) and SanLuis were obtained from Dr. Jorge Alberto Acosta‐Gallegos, Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP) Celaya, Mexico. Cranberry‐like bean Wit‐rood boontje and RILs obtained from a cross between Wit‐rood boontje and 1533‐13 were obtained from the University of Guelph, Canada.…”

Unravelling the Genetic Architecture of Rust Resistance in the Common Bean (Phaseolus vulgaris L.) by Combining QTL-Seq and GWAS Analysis

“…These genes belong to different gene pools: five genes including Ur-3 , Ur-5 , Ur-7 , Ur-11 and Ur-14 belong to the Middle American gene pool, while Ur-4 , Ur-6 , Ur-9 , Ur-12 and Ur-13 belong to the Andean gene pool [ 18 ]. Among these ten genes, the Ur-3 gene confers resistance to more than 50 races of the bean rust pathogen, and has been used extensively as the source of rust resistance in a large number of dry bean and snap beans cultivar in the United States, South Africa, and Middle American areas [ 19 , 20 , 21 , 22 ]. In addition, the Ur-13 gene has also played an important role in rust resistance breeding programs in South Africa [ 23 ].…”

Fine Mapping ofUr-3, a Historically Important Rust Resistance Locus in Common Bean

“…The Ur-3 gene present in the Middle American white-seeded common bean, Aurora, was reported by Ballantyne (1978) . Since then, this gene has been used extensively as the source of rust resistance in a large number of dry bean cultivars from various market classes of the United States, as well as in fresh market and processing snap beans ( Kelly et al 1994 ; Stavely et al 1997 ; Pastor-Corrales et al 2007 ; Urrea et al 2009 ; Osorno et al 2010 ; Brick et al 2011 ; Beaver et al 2015 ). Ur-3 has also been used as a source of rust resistance in dry bean cultivars of South Africa ( Liebenberg et al 2005 ).…”
