  1. Populations consist of CSLs with only a single substituted chromosome in a particular background plus their recurrent parent, a set of all sCSLs plus recurrent parents, or the complete set of CSLs, including parental genotypes. Regression models contain only backward selected parameters significantly contributing to explained variance. The parameters Chr1, Chr2, Chr3, Chr4 and Chr5 denote additive effects of individual chromosomes whereas BG denotes background effects. Parameter components separated by a colon indicate interaction effects.
