Plant genetic resources and climate change: threats and needs for adaptation through plant breeding

The need for food will continue to increase during the 21st century. By developing higher yielding, disease-resistant and adverse environment-tolerant crops, crop scientists will be at the forefront of the efforts to increase the global food supply. Over the past 50 years, there has been a three-fol...
