Simultaneous estimation of multiple quantitative trait loci and growth curve parameters through hierarchical Bayesian modeling.

A novel hierarchical quantitative trait locus (QTL) mapping method using a polynomial growth function and a multiple-QTL model (with no dependence in time) in a multitrait framework is presented. The method considers a population-based sample where individuals have been phenotyped (over time) with respect to some dynamic trait and genotyped at a given set of loci. A specific feature of the proposed approach is that, instead of an average functional curve, each individual has its own functional curve.

Properties of AFLP markers in inheritance and genetic diversity studies of pinus sylvestris L.

We analysed the properties of AFLP markers in Pinus sylvestris. Using primers with three selective nucleotides, the AFLP protocol produced large numbers of amplified bands and could only be used with a restricted number of primer combinations. Replacement of the EcoRI +3 primer by an EcoRI +4 primer halved the number of bands, facilitating analysis.

Theobroma cacao L.: a genetic linkage map and quantitative trait loci analysis.

A genetic linkage map of Theobroma cacao (cocoa) has been constructed from 131 backcross trees derived from a cross between a single tree of the variety Catongo and an F1 tree from the cross of Catongo by Pound 12. The map comprises 138 markers: 104 RAPD loci, 32 RFLP loci and two morphologic loci. Ten linkage groups were found which cover 1068 centimorgans (cM).
