Research advances in Chrysanthemum mapping populations

摘要：

　　Chrysanthemum (Chrysanthemum × morifolium) is one of the most popular ornamentals throughout the world, and a mapping population is a prerequisite for genetic mapping and QTL mapping of important ornamental traits as well as genetic linkage analysis.However, due to its high degree of heterozygosity and complex genetic background, the genetic research of chrysanthemum is relatively backward.A high-density genetic linkage map of chrysanthemum has not been established.In 2014, we established seven segregating biparental F1 populations by hybridization,including the diploid hybrids Chrysanthemum indicum var.aromaticum and Chrysanthemum lavandulifolium, the diploid and tetraploid hybrids C.indicum var.aromaticum and Chrysanthemum nankingense, the tetraploid and hexaploid hybrids C nankingense and cultivated varieties of chrysanthemum as well as the hexaploid hybrids.Compared to other progenies, the hexaploid hybrids were optimal for the construction of a genetic linkage map in chrysanthemum.
