Abstract

A world collection of 132 yellow mustard ( L.) accessions was characterized in a greenhouse to identify germplasm with polycotyledony and to assess the genetic segregation of tricot and tetracot seedlings in selfed S1 and S2 generations. The effort identified a set of 46 yellow mustard accessions with frequent occurrences of polycotyledony. The revealed genetic segregations seemed to suggest the development of tricot and tetracot seedlings in yellow mustard was largely controlled by a combination of genes at multiple diallelic loci. The identified tricot germplasm can be used to facilitate the genetic and/or genomic analysis of polycotyledonous germplasm for a better understanding of genetic and developmental mechanisms conditioning polycotyledony and the development of yellow mustard lines for explorable tricot breeding.

摘要

对来自世界各地的132份黄芥（L.）种质资源在温室中进行了鉴定，以识别具有多子叶的种质，并评估自交S1和S2代中三子叶和四子叶幼苗的遗传分离情况。这项工作鉴定出了一组46份经常出现多子叶的黄芥种质。所揭示的遗传分离似乎表明，黄芥中三子叶和四子叶幼苗的发育在很大程度上受多个双等位基因位点的基因组合控制。所鉴定出的三子叶种质可用于促进多子叶种质的遗传和/或基因组分析，以便更好地理解决定多子叶的遗传和发育机制，以及用于探索性三子叶育种的黄芥品系的培育。
