Understanding the quantitative genetics of crops has been and will continue to be central to maintaining and improving global food security. We outline four stages that plant breeding either has already achieved or will probably soon achieve. Top-of-the-line breeding programs are currently in Breeding 3.0, where inexpensive, genome-wide data coupled with powerful algorithms allow us to start breeding on predicted instead of measured phenotypes. We focus on three major questions that must be answered to move from current Breeding 3.0 practices to Breeding 4.0: (a) How do we adapt crops to better fit agricultural environments? (b) What is the nature of the diversity upon which breeding can act? (c) How do we deal with deleterious variants? Answering these questions and then translating them to actual gains for farmers will be a significant part of achieving global food security in the twenty-first century.

在育种4.0的道路上:阐明作物定量基因组学的好,坏和无聊

对作物的定量遗传学的了解一直并将继续对维持和改善全球粮食安全至关重要。我们概述了植物育种已经实现或可能很快实现的四个阶段。最先进的育种程序目前在Breeding 3.0中,在这里,廉价的全基因组数据与强大的算法相结合,使我们能够开始在预测的表型而不是在测量的表型上进行育种。从当前的育种3.0做法过渡到育种4.0,我们关注三个必须回答的主要问题:(a)我们如何调整作物以更好地适应农业环境?(b)育种可以采取行动的多样性的本质是什么?(c)我们如何处理有害的变体?回答这些问题,然后将其转化为农民的实际收益,将是实现二十一世纪全球粮食安全的重要组成部分。
