Yellow bean and slow-darkening pinto advanced breeding lines were tested in the preliminary and pre-coop yield trials at two locations. The lines were evaluated for maturity, growth habits, field disease resistance, yield potential and seed quality. Significant variation was observed in the breeding lines for resistance to common bacterial blight, maturity, lodging resistance, and yield potential. The unique hot and dry growing season in 2012 offered conditions for additional stress-tolerance selection, this was especially important considering the narrow genetic basis of these beans. The selections will be subjected to evaluation in 2013. Elite lines will be entered in to the 2013 Coop Trials. In addition, large numbers of selections were made in the early generation nurseries of both bean types. Crosses were also made to improve resistance to anthracnose and CBB in these two market classes.

Research Objectives
Evaluate approximately 45 new cultivars or advanced breeding lines each year in the MPGA Regional Trials at four locations (Morden, Winkler, Carman, and Portage la Prairie)
Evaluate approximately 55 advanced breeding lines each year in the Manitoba Cooperative Registration Trials at four locations
Evaluate yellow bean and slow-darkening pinto bean in F5 progeny rows in 2010, in preliminary yield trials in 2011, in pre-cooperative yield trials in 2012, and in the cooperative registration trials in 2013
Perform crosses and generate new breeding populations involving Peruano bean germplasm/breeding lines
Perform crosses and generate new breeding populations involving slow darkening pinto bean cultivar/germplasm
