产量是一个多因素的性状，整合了各种发育和生理过程。尽管有这种复杂性，但越来越多的证据表明，通过对单基因进行基因改造可以提高产量。针对不同的产量构成因素，取得了积极的效果，表明利用遗传手段进一步改良产量有很大的空间。成功的目标包括光合作用、淀粉生物合成、植物结构和控制植物发育的转录网络。目前的大多数数据是在(半)受控环境中获得的，并与以每株为基础计算的产量有关。证明将这些影响转移到田间种植的植物并参照单位面积产量的能力，将是确定这些发现的农学重要性的关键一步。
Yield is a multifactorial trait, integrating various developmental and physiological processes. Despite this complexity, evidence is mounting that yield can be increased by the genetic modification of single genes. Positive results have been obtained by targeting different yield constituents, indicating that there is ample room for further yield improvement by genetic means. Successful targets include photosynthesis, starch biosynthesis, plant architecture and transcriptional networks controlling plant development. Most of the current data have been obtained in a (semi-)controlled environment and relate to yield calculated on a per plant basis. Demonstrating the ability to transfer these effects to field-grown plants and with reference to yield on a per area unit basis will be a crucial step in establishing the agronomic importance of these findings.
