▪ Abstract Phenotypic variation for quantitative traits results from the segregation of alleles at
multiple quantitative trait loci (QTL) with effects that are sensitive to the genetic, sexual, and …

F ST and kinship are key parameters often estimated in modern population genetics studies
in order to quantitatively characterize structure and relatedness. Kinship matrices have also …

Further improvement of rice productivity remains a challenge. Breeding is perceived as an
important option to increase rice yield. However, the genetic progress of grain yield in most …

There is a growing need for the development of statistical techniques capable of mapping
quantitative trait loci (QTL) in general outbred animal populations. Presently used variance …

The aim of the MCQTL software package is to perform QTL mapping in multi-cross designs.
It allows the analysis of the usual populations derived from inbred lines and can link the …

The discovery of epistatically interacting QTL is hampered by the intractability and low power
to detect QTL in multidimensional genome searches. We describe a new method that maps …

To develop inbred lines, parents are crossed to generate segregating populations from
which superior inbred progeny are selected. The value of a particular cross thus depends on …

Abstract Analysis of quantitative trait loci (QTL) affecting complex traits is often pursued in
single-cross experiments. For most purposes, including breeding, some assessment is …

Key message In the QTL analysis of multi-parent populations, the inclusion of QTLs with
various types of effects can lead to a better description of the phenotypic variation and …

In the past decade plant geneticists began using complex plant populations to identify QTL
by association analysis, and the practice is becoming commonplace. Plant populations …
