Despite a huge population increase since the 1960s, the green revolution more than doubled world grain production and averted large-scale famine. Food crop productivity will have to be further raised, however, because the world population is still increasing rapidly. Among several parameters associated with the increase in yield potential, genes that control plant height and tiller number (in cereal crops) have recently been identified. In addition, a promising strategy to generate semi-dwarf varieties has been developed. Recent advances in plant genome analyses and plant biotechnology will realize a second green revolution through the genetic engineering of food crops.
尽管自20世纪60年代以来人口大幅增长，但绿色革命使世界粮食产量增加了一倍多，避免了大规模饥荒。然而，由于世界人口仍在迅速增长，粮食作物的生产力仍需进一步提高。在与产量潜力增加相关的几个参数中，控制株高和分蘖数（谷类作物）的基因最近已被确定。此外，还开发了一种培育半矮秆品种的有前景的策略。植物基因组分析和植物生物技术的最新进展将通过粮食作物的基因工程实现第二次绿色革命。
