Biparental mapping populations consist of a set of individuals derived from crosses between two parents often belonging to diverse species of a botanical genus and differing in terms of phenotype and traits to share. The development of such recombinant libraries represents a powerful strategy for dissection of the genetic basis of complex traits in crops and these are largely utilized to develop pre-breeding sources to use in crop improvement. This chapter provides an overview of methods and strategies to follow, for the construction of different types of populations, from a plant breeder point of view. Starting from the initial crossing between founder lines toward the further selection steps, here are described the populations commonly established in autogamous species including F, double haploids, backcrosses and recombinant inbreds, and introgression lines.
双亲作图群体由一组个体组成,这些个体通常来自两个亲本的杂交,这些亲本通常属于同一植物属的不同物种,在表型和性状方面存在差异,以便进行共享。此类重组文库的开发代表了一种用于解析作物复杂性状遗传基础的强大策略,这些文库主要用于开发用于作物改良的预育种源。本章从植物育种者的角度概述了构建不同类型群体的方法和策略。从最初的创始人系杂交开始,到进一步的选择步骤,描述了在自交物种中建立的常见群体,包括 F 群体、双单倍体、回交和重组自交系以及渐渗系。
