To feed the several billion people living on this planet, the production of high-quality food must increase with reduced inputs, but this accomplishment will be particularly challenging in the face of global environmental change. Plant breeders need to focus on traits with the greatest potential to increase yield. Hence, new technologies must be developed to accelerate breeding through improving genotyping and phenotyping methods and by increasing the available genetic diversity in breeding germplasm. The most gain will come from delivering these technologies in developing countries, but the technologies will have to be economically accessible and readily disseminated. Crop improvement through breeding brings immense value relative to investment and offers an effective approach to improving food security.
为了养活这个星球上的几十亿人口，必须以减少投入的方式来增加高质量食物的产量，但在面对全球环境变化时，这一目标将极具挑战性。植物育种者需要专注于具有最大增产潜力的性状。因此，必须开发新技术，通过改进基因型和表型鉴定方法以及增加育种种质的遗传多样性来加速育种进程。发展中国家将获得最大收益，但这些技术必须具有经济可行性，并且易于传播。通过育种进行作物改良相对于投资而言具有巨大的价值，并且是提高粮食安全的有效途径。
