Description of Baetao‐Manteiga 41 and 'Yunguilla' superior Andean common beans for Tanzanian production environments.

An international effort was initiated with the evaluation of a diverse set of large‐seeded Andean common beans (Phaseolus vulgaris L.), the Andean Diversity Panel, in sub‐Saharan Africa. Several entries in the panel have been selected for extensive characterization on the basis of high performance across multiple location × year trials in Tanzania—conducted both on station and on farm. Baetao‐Manteiga 41, tested as ADP‐190, has a commercial Kablanketi (light purple speckled) seed type, and 'Yunguilla', tested as ADP‐447, has a commercial Calima (red mottled) seed type. Both lines exhibited yield stability, vigorous growth under low fertility conditions, angular leaf spot resistance, and moderate common bacterial blight resistance; Yunguilla also possessed rust resistance. These two lines were tested, selected, and characterized cooperatively by Sokoine University of Agriculture (SUA), the Tanzanian Agricultural Research Institute (TARI), the USDA‐ARS, and the Agricultural Research Council (ARC) of South Africa, and in collaboration with local farmers in Tanzania.
