Interpretive Summary: ‘Kikatiti’ pinto bean was developed by the dry bean breeding program at the University of Nebraska, Agricultural Research Division and was released in 2020 by Sokoine University of Agriculture in Morogoro as an upright indeterminate pinto bean with high yield potential and multiple disease resistance across Tanzania production environments. Kikatiti was developed using the pedigree breeding method in Nebraska. The exceptional performance of Kikatiti in Tanzania was first identified by evaluation of the Durango Diversity Panel (DDP) which consisted of 200 accessions. Kikatiti was accession DDP-094 (advanced breeding line NE2-09-3). Kikatiti yielded 1584 kg ha-1 across five years of trials in Tanzania, and matured in 89 days. Kikatiti is resistant to the rust fungal disease, resistant to BCMV and BCMNV viral diseases, moderately resistant to the common bacterial blight disease, avoids white mold disease due to its upright architecture, and is moderately susceptible to angular leaf spot disease. Kikatiti has a large seed size (35.9 g 100 seeds-1), and in on-farm trials, farmers ranked Kikatiti above local pinto cultivars for its high performance and good market potential. Kikatiti has the potential to support and expand pinto bean production across East Africa.

Technical Abstract: ‘Kikatiti’ pinto bean (Phaseolus vulgaris L.) was developed by the dry bean breeding program at the University of Nebraska, Agricultural Research Division and was released in 2020 by Sokoine University of Agriculture in Morogoro as an upright indeterminate pinto bean with high yield potential and multiple disease resistance across Tanzania production environments. Kikatiti is an F7:8 derived line developed using the pedigree breeding method in Nebraska. The exceptional performance of Kikatiti in Tanzania was first identified by evaluation of the Durango Diversity Panel (DDP) which consisted of 200 accessions. Kikatiti was accession DDP-094 (advanced breeding line NE2-09-3). Kikatiti yielded 1584 kg ha-1 across five years of trials in Tanzania, and matured in 89 d. Kikatiti is resistant to rust conferred by the Ur-3 and Ur-11 genes, resistant to all strains of BCMV and BCMNV conferred by the I and bc-3 genes, moderately resistant to common bacterial blight conferred by the SAP6 QTL, avoids white mold disease due to its upright architecture, and is moderately susceptible to angular leaf spot disease. Kikatiti has large seed size (35.9 g 100 seeds-1), and in on-farm trials, farmers ranked Kikatiti above local pinto cultivars for its high performance and good market potential. Kikatiti has the potential to support and expand pinto bean production across East Africa.
