An analysis of major U.S. crops shows that there is a large genetic potential for yield that is unrealized because of the need for better adaptation of the plants to the environments in which they are grown. Evidence from native populations suggests that high productivity can occur in these environments and that opportunities for improving production in unfavorable environments are substantial. Genotypic selection for adaptation to such environments has already played an important role in agriculture, but the fundamental mechanisms are poorly understood. Recent scientific advances make exploration of these mechanisms more feasible and could result in large gains in productivity.
对美国主要农作物的分析表明，由于需要更好地使这些植物适应其生长的环境，存在大量尚未实现的产量遗传潜力。来自本地种群的证据表明，在这些环境中可以实现高生产力，并且在不利环境中提高产量的机会很大。对适应这些环境的基因型选择在农业中已经发挥了重要作用，但基本机制尚不清楚。最近的科学进展使对这些机制的探索变得更加可行，并可能带来生产力的大幅提高。
