从实验杂交中获得的作物群体使复杂性状的遗传解剖成为可能，并支持现代植物育种。其中，多亲本种群现在起着核心作用。通过混合和重组多个始祖的基因组，多亲本群体结合了许多普遍寻求的遗传作图群体的有益特性。例如，它们具有定位数量性状位点的高能力和分辨率、高遗传多样性和最小群体结构等特点。在作物物种中建立了许多多亲本群体，其自交系种质及其相关表型和基因型数据是持久的资源。它们的用途已经从绘制数量性状位点的工具发展成为为育种计划提供种质资源的手段。基因组学方法，包括从头基因组组装和群体创始人的基因注释，已经允许将丰富的序列信息输入后代群体，扩大了多亲本群体的研究和育种应用的广度。在这里，我们报告了最近在作物多亲本群体中取得的成功。我们还提出了一个理想的基因型、表型和种质“包”，多亲本群体应该以其为特征，以优化其作为作物研究、开发和育种的强大社区资源的利用。
Crop populations derived from experimental crosses enable the genetic dissection of complex traits and support modern plant breeding. Among these, multi-parent populations now play a central role. By mixing and recombining the genomes of multiple founders, multi-parent populations combine many commonly sought beneficial properties of genetic mapping populations. For example, they have high power and resolution for mapping quantitative trait loci, high genetic diversity and minimal population structure. Many multi-parent populations have been constructed in crop species, and their inbred germplasm and associated phenotypic and genotypic data serve as enduring resources. Their utility has grown from being a tool for mapping quantitative trait loci to a means of providing germplasm for breeding programmes. Genomics approaches, including de novo genome assemblies and gene annotations for the population founders, have allowed the imputation of rich sequence information into the descendent population, expanding the breadth of research and breeding applications of multi-parent populations. Here, we report recent successes from crop multi-parent populations in crops. We also propose an ideal genotypic, phenotypic and germplasm ‘package’ that multi-parent populations should feature to optimise their use as powerful community resources for crop research, development and breeding.
