Greater focus on climate change and sustainable production will be key breeding goals of the future. Global climate changes underscore the strong justification for continuous public breeding efforts to preserve bean yield potential through breeding of improved resistance to rapidly evolving biotic and abiotic stresses and the continued displacement of bean production to less favorable environments across the globe.

A 2010 study demonstrated the importance of maintenance breeding as it relates to climate. It was found the 15% reductions in present‐day yield of IR8, the miracle rice variety developed over 50 years ago resulted from the lack of adaptation to current environmental conditions (Peng et al. 2010). The authors stressed the critical role that breeding plays in improving the adaptation of newly developed varieties to changing climatic conditions that have a negative impact on older varieties. The same holds true for bean breeding.
