Details for: PI 653258, Phaseolus vulgaris L., 'HUNGERFORD'

Extra-large-seeded Hungerford great northern dry bean has an indeterminate semi-prostrate growth habit Type III with medium to large vine. The central leaflet of fully developed trifoliolate leaf is of ovate shape with average length of 9.5 cm and width of 7.5 cm. The flower bracteoles are of chordate shape and medium size. Flower color is white with the absence of stripes at the outer base of the standard. Pods of Hungerford at maturity are flat and curved with curved-down beak, tan or yellowish-brown with light purple stripes and an average of 4-5 seeds. Hungerford has mean maturity of 95 d in southern Idaho with yield of 1995 lbs A-1. Mean 100-seed weight of Hungerford was 40 g in Idaho and 44 g in the Western Regional Bean Trial. Hungerford has the dominant I gene resistance to BCMV strains NY-15 and US-6. However, when inoculated with the BCMNV strain NL-3K, Hungerford exhibits top or systemic necrosis including black root. It has SCAR marker SW 13. Hungerford is resistant to race 38 of U. appendiculatus, but exhibits small pustules when exposed to race 53. Hungerford is susceptible to anthracnose, common bacterial blight, Fusarium root rot, halo blight, and white mold. Hungerford is moderately susceptible to BCTV. Hungerford has moderate to high levels of resistance to heat, intermittent drought, and to soil zinc deficiency and manganese toxicity. Hungerford was developed for 95 to 100 days frost-free bean production regions of southern Idaho. However, Hungerford has exhibited a broad adaptation in relatively warmer bean growing environments in the Western USA. Because of its semi-prostrate growth habit and lack of resistance to anthracnose and white mold Hungerford may have limited adaptation in or not suited to the relatively cool and wet production environments.
