Toelichting (Engels) In this research, a M. sinensis collection of the Laboratory of Plant Breeding from Wageningen University was characterized based on morphological and cell wall traits. To achieve a better insight miscanthus breeding, variation and trait correlations for morphological and biomass quality characteristics, relevant for the improvement of M. sinensis in the con text of a bio-based economy, were investigated. Cell wall trait s were predicted using NIR - based prediction models, which were actualized and improved using biochemical analysis. For both morphological traits as cell wall traits high variation was observed in the collection, together with plenty different trait combinations, resulting in a broad base of potential parental lines for all kind of breeding purposes. Dry matter yield showed a wide range of variation (~200 to ~3900 g) with an average of 1600 grams per 4 plants, of which 87% of dry mass consisted of cell wall material. From total dry mass, cellulose (~40 to ~54%), hemicellulose (~25 to ~34%) and lignin (~5 to ~11%) were the main constituents. For a mild pre - treatment, cellulose conversion ranged from ~30 to ~44%, which was about the same range as for hemicellulose conversion (~28 to ~43%) . In general, accessions that represent ed a high sugar yield show ed high dry mass yields together with a low cell wall conversion efficiency, except for one. This shows both the challenge as the high potential of M. sinensis breeding for bio-based purposes to combine these traits to develop miscanthus as a bioenergy crop.
