Biparental recombinant inbred line (RIL) populations are sets of genetically stable lines and have a simple population structure that facilitates the dissection of the genetics of interesting traits. On the other hand, populations derived from multiparent intercrosses combine both greater diversity and higher numbers of recombination events than RILs. Here, we describe a simple population structure: a three-way recombinant inbred population combination. This structure was easy to produce and was a compromise between biparental and multiparent populations. We show that this structure had advantages when analyzing cultivar crosses, and could achieve a mapping resolution of a few genes.
双亲重组近交系（RIL）群体是一组遗传稳定的品系，具有简单的群体结构，便于对有趣性状的遗传进行剖析。另一方面，由多亲杂交产生的群体结合了比 RIL 更高的多样性和更多的重组事件。在这里，我们描述了一种简单的群体结构：三向重组近交群体组合。这种结构易于产生，是双亲与多亲群体之间的折衷。我们表明，这种结构在分析品种杂交时具有优势，并且可以达到几个基因的作图分辨率。
