Interpretive Summary: Pinto bean is the most important market class in the US. Pinto beans with early maturity, upright architecture and disease resistance are desired by growers. Three new pinto bean cultivars are being released to growers for production primarily in the Pacific Northwest. These cultivars with early maturity extends the planting season, reduces the frequency and amount of irrigation water required, minimizes risks from early frosts, and facilitates availability of freshly harvested beans to market place early in the season. These cultivars with erect, upright growth habits facilitate mechanical field management including one-step-direct-cut harvest, improve seed quality and recovery percentage, and reduce disease incidence and production costs. Lastly, these cultivars exhibit resistance to virus diseases prevalent in the Western US and rust disease which is problematic east of the Continental Divide.
Technical Abstract: Pinto common bean cultivars Blackfoot (Reg. No. -----,), Nez Perce (Reg. No. -----, PI), and Twin Falls (Reg. No. -----,) were developed at the University of Idaho-Kimberly Research and Extension Center in collaboration with researchers in Colorado, Nebraska, and Washington State. Twin Falls is a full-season (108 d to maturity), Blackfoot is an early (86 d to maturity), and Nez Perce is a medium (94 d to maturity) maturity pinto bean cultivar in southern Idaho. The pinto UIP 40 bulk from which Twin Falls was selected was tested in the Western Regional Bean Trial (WRBT) in 2014 and 2015 and in the Cooperative Dry Bean Nursery (CDBN) in 2015. The UIP 40 has the pedigree USPT-CBB-1///CO 12650/USPT-ANT-1//‘Othello’/ABL 15. Blackfoot and Nez Perce were tested in the same WRBT and CDBN as and selected from the UIP 35 bulk derived from population USPT-CBB-1/4/Othello/‘UI 906’//‘Topaz’/‘Buster’. The three are the first upright erect growth habit Type II pinto bean cultivars developed at University of Idaho. Furthermore, Blackfoot and Nez Perce are the first early and medium maturing pinto bean cultivars developed at University of Idaho. The three pinto bean cultivars are resistant to bean rust [caused by Uromyces appendiculatus (Pers.:Pers.) Unger] and soil iron and zinc deficiencies.
