ABSTRACT

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.
