Despite recent achievements in conventional plant breeding and genomics, the rate of increase of crop yields is declining and thus there is a need for a second green revolution. Advances within single disciplines, alone, cannot solve the challenges of increasing yield. As scientific disciplines have become increasingly diversified, a more complete understanding of the mechanisms by which genetic and environmental variation modify grain yield and composition is needed, so that specific quantitative and quality targets can be identified. To achieve this aim, the expertise of plant genomics, physiology and agronomy, as well as recently developed plant modelling techniques, must be combined. There has been recent progress in these individual disciplines, but multidisciplinary approaches must be implemented to tackle drought stress and salinity as major constraints to achieving sufficient grain yield in the future.
尽管传统植物育种和基因组学领域近期取得了一些成果，但作物产量的增长速度正在下降，因此需要开展第二次绿色革命。仅靠单一学科的进展无法解决提高产量的挑战。随着科学学科日益多样化，需要更全面地了解遗传和环境变异影响谷物产量及构成的机制，以便确定具体的产量和品质目标。为实现这一目标，必须将植物基因组学、生理学和农学的专业知识以及最近开发的植物建模技术结合起来。这些学科各自都取得了一些进展，但必须采用多学科方法来应对干旱胁迫和盐碱化问题，因为这两个问题是未来实现足够谷物产量的主要制约因素。
