Recommendations for the choice of miscanthus genotypes for different European regions.
| Genotype ID | Recommended | Reason |
|---|---|---|
| OPM-01 (M. sac) | No | Poor yields, spreading (creeping) rhizome. |
| OPM-02 (M. sac) | Sometimes | Only in southern Europe with irrigation where drought possible. Excellent yield but requires high temperatures and susceptible to drought. Has spreading rhizome but can be managed by mowing field plot borders once or twice mid-season. |
| OPM-03 (M. sac) | Sometimes | Mainly in southern Europe with irrigation where drought is possible; also possible for Central Europe. High yielding in some locations. It has a spreading rhizome but can be managed by mowing field plot borders once or twice mid-season. |
| OPM-4 (M. sac) | No | Poor yields and a spreading rhizome. |
| OPM-05 (M. sac × M. sin) | No | Acceptable yield but out-performed by similar hybrids. |
| OPM-06 (M. sac × M. sin) | Yes | Central and eastern parts of northern Europe. Excellent yields but lodging crop not acceptable to farmers. |
| OPM-07 (M. sac × M. sin) | No | Poor yields. |
| OPM-08 (M. sac × M. sin) | Yes | Northern Europe. Excellent yields at the cooler sites. |
| OPM-09 (M. x gig) | Yes | Most of Europe. Excellent yields generally sufficient for large areas of Europe, especially with the projected climate changes of warmer wetter winters, which is consistent with the years these trials were conducted. Limited by clonal propagation. |
| OPM-10 (M. sac × M. sin) | Yes | Most of Europe. Excellent yields and low moisture content at harvest on account of early senescence. |
| OPM-11 (M. sin) | Yes | Southern Europe. Good yields at the locations with warm summers and frequent droughts (this clone did not perform well in Aberystwyth or Moscow). |
| OPM-12 (M. sin) | No | This seeded germplasm entry is heterogeneous. It flowers too early to attain high yields. It produces viable seeds. (In the WP4 trials, establishment problems were largely linked to logistical issues around planting, rather than being a reflection of germplasm establishment ability.) |
| OPM-13 (M. sin) | Yes | Potential in areas with warm summers and drought. Advantages: seed-based and non-creeping. More homogeneous than OPM-12 and OPM-15. Generally lower yielding than interspecies hybrids. It was less susceptible to drought conditions in Turkey. |
| OPM-14 (M. sin) | Yes | Southern Europe. Similar to OPM-13, but on average slightly lower yielding. |
| OPM-15 (M. sin) | No | As for OPM-12. This seeded germplasm entry is heterogeneous. It flowers too early to attain high yields. It produces viable seeds. |
