Narrative
SB-DT2 (Reg. No. GP-____, ____) is a pinto bean germplasm developed through shuttle breeding between Nebraska and Puerto Rico with broad temperate and tropical adaptation. SB-DT2 gerplasm was developed through combining drought tolerance from the common bean Mesoamerican and Durango races and within the Mesoamerican race. In addition to drought stress tolerance, SB-DT2 showed resistance to endemic strains of the rust pathogen at Fort Collins, CO caused by Uromyces appendiculatus. SB-DT2 carries the single dominant hypersensitive I gene that provides strain non-specific resistance to the bean common mosaic virus (BCMV). The Intertek snpPV0072 confirmed the presence of the I gene, while the absence of the bc3 gene was confirmed with the eIF4E CAPS marker. Under drought stress, SB-DT2 flowered at 44 d, and matured d after planting, and is adapted to both temperate and tropical production environments. This germplasm was developed cooperatively by the University of Nebraska and the USDA-ARS.

Pedigree
Description:
SB-DT2 (tested as SB-815) was developed from the cross of USPT-ANT//’Matterhorn’/98078-5-1-5-1. Matterhorn is a drought tolerant great northern cultivar with high general combining ability, and USPT-ANT is a pinto bean with anthracnose resistance. The breeding line 98078-5-1-5-1 was developed at USDA-ARS-TARS from the cross ‘Chase’/’Glacier’.
