The aim of this work was the identification of polymorphisms within candidate genes from the lignin biosynthesis pathway with possible influence on the silage quality of maize. To achieve this goal, partial or complete genomic sequences from up to 40 independent maize inbreds were obtained and analysed using an association mapping approach. Fife of the analysed 8 loci showed polymorphisms with significant association with the variation of some of the measured maize quality criteria. Several polymorphisms were located in the COMT locus, which is known for a naturally occurring mutation resulting in drastic improvement of maize digestibility. Furthermore, the vulnerability of association studies to false positives was assayed using 9 polymorphisms within the Dwarf8 locus, that were genotyped at 71 maize inbreds. The significant correlation of this polymorphisms with flowering time, previously found in a former study, could be only confirmed when the genetically inferred population structure was not considered.
