Abstract: Miscanthus is a genus of high-yielding perennial rhizomatous grasses with C photosynthesis. Extensive field trials of Miscanthus spp. biomass production in Europe during the past decade have shown several limitations of the most widely planted clone, M. x giganteus Greef et Deu. A 3-yr study was conducted at five sites in Europe (Sweden, Denmark, England, Germany, and Portugal) to evaluate adaptation and biomass production potential of four acquisitions of M. x giganteus (No. 1–4) and 11 other genotypes, including M. sacchariflorus (Maxim.) Benth. (No. 5), M. sinensis Andersson (No. 11–15), and hybrids (No. 6–10). At each site, three randomized blocks containing a 5- by 5-m plot of each genotype were established (except in Portugal where there were two blocks) with micropropagated plants at 2 plants m2. In Sweden and Denmark, only M. sinensis and its hybrids satisfactorily survived the first winter following planting. Mean annual yields across all sites for all surviving genotypes increased each year from 2 t ha-1 and 18 t ha-1dry matter following the first year of growth to 9 following the second and third year, respectively. Highest autumn yields at sites in Sweden, Denmark, England, and Germany were 24.7 (M. sinensis hybrid no. 8), 18.2 (M. sinensis hybrid no. 10), 18.7 (M. _ giganteus no. 3), and 29.1 t ha-1 (M.x giganteus no. 4), respectively. In Portugal, where irrigation was used, the top-yielding genotype produced 40.9 t ha-1 dry matter (M. sinensis hybrid no. 7). Highest-yielding genotypes in Sweden and Denmark were among the lowest yielding in Portugal and Germany, demonstrating strong genotype x environment interactions.
