What is it about?
To inform population improvement strategies and selection decisions for resilient fast cooking and iron biofortified beans, the study determined diversity and population structure within 427 breeding lines, varieties, or landraces mostly from Alliance Uganda and Columbia. Performance ranged from 52 to 87 ppm (iron), 23–38 ppm (zinc), 36–361 minutes (cooking time), and 397–1299 kg/ha (yield). Minimal differences existed between the gene pools in the mean performance except in yield, where Mesoamerican beans were better by 117 kg/ha. The genotypes exhibited high genetic diversity and thus have a high potential for use in plant breeding.

Why is it important?
The population was clustered into three groups that could be considered for specific breeding targets based on trait correlations.
