Plant Breeding Must Adapt To Climate Change, Finds Study

By Sarah McLaughlin

Breeding is a vital part of the global agrifood system, enabling scientists to adapt crops to developing environmental factors, support improved crop management, and inform policy interventions on global food production. The challenge to crop breeding increases every year, as farmers experience more of the effects of climate change, while the population and food demand continue to rise.

Research by the International Maize and Wheat Improvement Center (CIMMYT) has determined that climate change is affecting the objectives, efficiency, and genetic gains of current plant breeding, causing limitations to the breeding approach of the next generation.

The study found that climate change necessitates a faster breeding cycle and must drive changes in breeding objectives by putting climate resilience as the top priority.

“The risk of multiple crop failure due to climate change is very real. Breeding must become more deterministic in terms of adaption if we are to avert food price-hikes, hunger, and social unrest,” said Matthew Reynolds, Distinguished Scientist and Head of Wheat Physiology at CIMMYT.
