Abstract

Abstract : Pinto bean ( Phaseolus vulgaris L.) cultivars 'Blackfoot' (Reg. No. CV‐316, PI 680632), 'Nez Perce' (Reg. No. CV‐317, PI 680633), and 'Twin Falls' (Reg. No. CV‐318, PI 680634) were developed at the University of Idaho, Kimberly Research and Extension Center in collaboration with researchers in Colorado, Nebraska, and Washington. Blackfoot and Nez Perce are sister cultivars derived from the same bulk population, UIP35 (USPT‐CBB‐1/3/'Othello'/'UI 906'//'Topaz'/'Buster'). Twin Falls was selected from the bulk population UIP40 (USPT‐CBB‐1/3/CO12650/USPT‐ANT‐1//Othello/ABL15). The F8 of both population bulks and checks were yield tested in the Western Regional Bean Trial in 2014 and 2015 and in the Cooperative Dry Bean Nursery in 2015. The three cultivars were yield tested in Idaho in 2015. They were also yield tested across nine production environments in Colorado, Idaho, Nebraska, and Washington in 2016. Blackfoot, Nez Perce, and Twin Falls are the first indeterminate erect Type II growth habit pinto bean cultivars resistant to Bean common mosaic virus (an aphid‐vectored potyvirus) and bean rust developed at University of Idaho. Blackfoot has a compact Type IIA growth habit and produces little or no vine (i.e., elongated terminal axis with intertwined internodes that help the plant climb when provided support). In contrast, Nez Perce is tall and produces medium to long vines, with a Type IIB growth habit. Blackfoot has a mean maturity of 85 d and Nez Perce 95 d in southern Idaho. Twin Falls is a full‐season cultivar (≥100 d) and relatively tall, with very small or no vines for climbing. The three cultivars have relatively smaller seed (<35 g 100 −1 seeds) than early‐maturity pinto 'Othello' (≥35 g 100 −1 seeds) in the Pacific Northwest.
