Effects of environment and progeny on biomass estimations of five hybrid poplar families grown at three contrasting sites across Europe Inra

The quantitative and qualitative estimation of aboveground previous termbiomassnext term production is essential for short-rotation forestry. Indirect methods of previous termbiomassnext term estimation have been developed based on the establishment of regressions between previous termbiomassnext term components and tree dimensions as well as canopy architecture. The difficulty encountered with this method is to know whether, and to what degree, the obtained equations can be used under contrasting environmental conditions and for different genetic backgrounds. In the present study, allometric equations were developed linking tree dry weight (stem, branch and aboveground tree dry weight) with stem circumference, stem height and number of sylleptic branches...

Genomic regions involved in productivity of two specific poplar families in Europe. 2. Biomass production and its relationships with tree architecture and phenology Inra
Marron, N.; Storme, V.; Dillen, S.Y.; Bastien, C.; Ricciotti, L.; Salani, F.; Sabatti, M.; Rae, A.M.; Ceulemans, R.; Boerjan, W..
Short-rotation coppice of hybrid poplar is a promising renewable feedstock for biofuel production. Breeding for high biomass in short-rotation coppice has started only recently. Two hybrid poplar families were grown at two sites in Europe and phenotyped for a variety of biomass-related traits (1) to examine the extent of phenotypic and genetic variation in biomass production, ramification, resprouting, and phenology, (2) to search for genomic regions involved in productivity, and (3) to determine the effect of the environment on the expression of these traits. The performance of both families differed within and among sites. A pronounced heterosis was observed in most cases. Moderate to high heritability values were found. Seventeen quantitative trait loci...
