对美国主要农作物的分析表明，由于需要更好地适应植物生长的环境，产量的遗传潜力尚未实现。来自土著居民的证据表明，在这些环境中可以产生高生产力，在不利的环境中提高生产力的机会是巨大的。适应这种环境的基因型选择已经在农业中发挥了重要作用，但对基本机制知之甚少。最近的科学进展使探索这些机制更加可行，并可能导致生产力的大幅提高。
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.
