Résumé

Wild populations of Salix (willow) species can provide large reservoirs of natural phenotypic and genotypic variation relevant to environmentally and industrially important traits. Focussing on pan-Canadian collection of the AgCanSalix (Agriculture Canada Salix) collection, our specific goals were to thoroughly understand the intraspecific variation in biomass accrual and cell wall trait variations, and to use this information to accelerate Salix breeding and selection in Canada. By making use of over 500 Salix eriocephala genotypes sampled from its natural range across Canada, we studied variation in seasonal phenology, growth physiology and wood physio-chemical properties planted into a common garden at Indian Head, Saskatchewan (50.33°N, 103.39°W). These data, in addition to single nucleotide polymorphisms revealed patterns of genetic diversity and population structure, mainly shaped by geography, which is correlated with local frost-free days and mean annual precipitation. The speaker will highlight selected examples of the results of these analyses, and their potential applications for bioenergy, phytoremediation of saline and nutrient-rich sites, and value added bioproducts (such as, biochar) will be discussed.
