Abstract
Chrysanthemums (Chrysanthemum indicum hybrid) are one of the most important ornamental plants with a large variation for different phenotypic traits; however, there is only limited data about the inheritance of these traits or corresponding marker-trait aßociations. We phenotyped and genotyped two types of chrysanthemum populations with the main focus on shoot branching: a collection of 86 cultivars and a biparental F1-population of 160 individuals. We identified 15 marker-trait aßociations with AFLP markers for the genotype collection using a genome-wide aßociation study and 17 marker-trait aßociations for the population by applying a single locus analysis. Additionally, we started a candidate gene approach for strigolactone pathway genes to identify marker alleles that are significantly aßociated with shoot branching. First results indicate, that these genes describe a large proportion of the variation in shoot branching in these populations. This highlights the role of the strigolactone pathway and indicates that shoot branching in the chrysanthemum has a polygenic inheritance pattern, though other yet unknown factors are also likely involved. Although nearly all of the investigated traits were characterized by a continuous variation in phenotypic values, as was expected for the outcroßing hexasomic nature of the chrysanthemum, we identified informative marker-trait aßociations with important characteristics.
