The interspecific breeding line VRW 32 (Reg. No. GP-287, PI 665037) of common bean (Phaseolus vulgaris L.), which is resistant to white mold [caused by Sclerotinia sclerotiorum (Lib.) de Bary], was jointly developed at

Pinto dry bean (Phaseolus vulgaris L.) ‘Kimberly’ (Reg. No. CV‐283, PI 653256) and ‘Shoshone’ (Reg. No. CV‐284, PI 653257) were developed at the University of Idaho‐Kimberly Agricultural Research and Extension Center. Both were released by the Idaho Agricultural Experiment Station on 12 Apr. 2007. Kimberly is a full‐season (100 d to maturity) and Shoshone is an early‐ to medium‐maturing cultivar. Both have light‐colored and slow‐darkening pinto seed. Both are high‐yielding, widely adapted cultivars and possess the bc‐3 and I genes imparting resistance to all strains of Bean common mosaic virus and Bean common mosaic necrosis virus (an aphid‐vectored potyvirus) and to rust [caused by Uromyces appendiculatus (Pers.) Ung.]. Both also have moderate to high levels of resistance to heat and drought. However, both are susceptible to soil zinc deficiency and manganese toxicity.

Availability of germplasm with high level of resistance is essential for broadening the genetic base and breeding crop cultivars resistant to abiotic and biotic stresses. The objective of this study was to determine reaction of a common bean core collection from the Iberian Peninsula to anthracnose, rust, common and halo blights, bean common mosaic virus (BCMV, a potyvirus) and bean common mosaic necrosis virus (BCMNV, a potyvirus) pathogens. Of 43 accessions evaluated, 14 large-seeded Andean type, seven small-seeded Middle American type and seven with intermediate characteristics or recombinant type between the two gene pools had resistant reaction to one or more diseases. Resistance to race 17 or 23 of anthracnose pathogen was present in 17 accessions and four accessions were resistant to both races. Resistance to race 38 or 53 of rust pathogen was shown by 22 accessions and five accessions were resistant to both races. All accessions were susceptible to common bacterial blight and 12 accessions had resistance to halo blight. Ten accessions showed resistance to BCMV, none to BCMNV, and two were variable to both viruses. Accessions such as PHA-0573 (pinto), PHA-0589 (marrow), PHA-0654 (favada pinto), and PHA-0706 (favada) showed resistance to two or more diseases. These accessions may be valuable in breeding Andean bean for enhancing simultaneous utilization of both large seed size and disease resistance.

Large‐seeded (45 g 100 seed weight−1), high‐yielding, and high‐quality Hungerford (Reg. No. CV‐285, PI 653258) and Sawtooth (Reg. No. CV‐286, PI 653259) great northern dry bean (Phaseolus vulgaris L.) cultivars were developed at the University of Idaho‐Kimberly Agricultural Research and Extension Center. The Idaho Agricultural Experiment Station released Hungerford and Sawtooth on 12 Apr. 2007. Hungerford and Sawtooth are full‐season (95–100 d maturity) cultivars adapted to the western United States that have resistance to Bean common mosaic virus (an aphid‐vectored potyvirus) and rust [caused by Uromyces appendiculatus (Pers.) Ung.]. Both also have moderate to high levels of resistance to heat, drought, and soil zinc deficiency and manganese toxicity.
