“…Important characteristics of some interspecific hybrids are high growth rates and broad applicability ranging from wood and paper to energy production (Dickmann and Stuart, 1993 (Fladung et al, 2012) and the availability of huge genomic resources (Stettler et al, 1996;Stanton et al, 2010). Superior clones of various Populus species have been developed and are commonly used for biomass production in short rotation plantations.…”

Populus trichocarpa and P. deltoides are the only Populus species known to date to have a publicly available nuclear genome sequence that has been assembled to chromosomes and annotated (https://phytozome.jgi.doe.gov/). Here we focus on the clone INRA 717-1B4, a female P. tremula x P. alba (P. x canescens) interspecific hybrid that is universally used by scientists worldwide as a tree model in transgenic experiments. The already available INRA 717-1B4 nuclear genomic resource (v1.1 of sPta717 at http://aspendb.uga.edu/index.php/databases/ spta-717-genome) presents only INRA 717-1B4 genomic regions with high similarity to the P. trichocarpa genomic reference sequences. We assembled draft genomic scaffolds by a combination of de novo assembly with reference-based assembly using 30x resequencing NGS data (Illumina MiSeq® and Ion Torrent Ion PGM™) of INRA 717-1B4. In total, 419,969 scaffolds of length larger than 500 bp were generated. The mean length of the scaffolds is 2,166 bp and the size of the largest scaffold 84,573 bp. The N50 contig length is 3,850 bp when considering contigs larger than 1,000 bp. Probably due to the high level of heterozygosity of this interspecific hybrid, the accumulated scaffold length is with 0.9 GB about twice the expected size of the haploid nuclear genome. DNA sequences of the genomic scaffolds of INRA 717-1B4 are publicly available for Blast analyses and download via the new INRA web portal at https://urgi. versailles.inra.fr/Species/Forest-trees/Populus/Clone-INRA-717-1B4/. This new genomic sequence resource will complement the already available INRA 717-1B4 resources and will facilitate the future optimization of genetic transformation experiments to discover gene function.

“…Considerable breeding efforts have produced a number of fastgrowing poplar cultivars (Stanton et al 2010;Karp et al 2011); these are derived almost entirely from interspecific crosses (Benetka et al 2014). In Europe, new poplar hybrids are mainly derived from crosses between the s. Aigeiros species P. deltoides and P. nigra, and called P. × canadensis Moench (Bisoffi and Gullberg 1996), or between the s. Aigeiros species P. nigra with the s. Tacamahaca species P. maximowiczii (Stanton et al 2010). In Poland, there is a long tradition of growing hybrid NE-42 (known in Poland as 'Hybrida 275') that was produced from the s. Tacamahaca species cross P. maximowiczii × P. trichocarpa.…”

Background: Renewable energy sources such as biomass are an important aspect of the energy policy of the European Union. As the use of 'full-value wood' for energy purposes has been restricted, short-rotation forestry may be an alternative source of woody biomass. In Poland, the most promising genus is poplar (Populus spp.). Methods: Ten poplar cultivars from the Aigeiros or Tacamahaca sections of the genus Populus were compared in 5-and 6-year rotations for biomass components and yields. Additional aims were to preliminarily (a) identify a suitable rotation length and (b) evaluate the sprouting capacity of various cultivars in the climate of northern Poland. The following variables were measured: diameter at breast height (DBH), height, survival rate, single-tree dry mass, crop biomass production, and sprouting ability. Results: The cultivars 'NE-42' and 'Fritzi Pauley' showed the best growth characteristics (DBH and height) and highest biomass production (7.6 and 7.7 t ha −1 year −1 , and 5.2 and 6.9 t ha −1 year −1 , respectively, for cultivars in the 5-and 6-year cycles). These cultivars were also distinguished by a large number of coppice shoots and a high shoot length. Eight cultivars did well enough to produce worthwhile data, and five of these gave higher biomass production (t DM ha −1 year −1 ) during the 6-year, as opposed to the 5-year cycle. Of the eight cultivars analysed, 'AF-8' had the poorest growth parameters and produced two thirds less dry biomass than either the 'NE-42' or 'Fritzi Pauley' cultivars. Data for two Italian cultivars ('AF-6' and 'MON') were not analysed because of their cold tenderness and their high mortality. Conclusions: Rotation length is important for biomass production in energy plantations. Most of the tested poplar cultivars gave higher biomass productivity over an initial 6-year cycle than over a 5-year one. Our preliminary results suggest that the 'NE-42' and 'Fritzi Pauley' cultivars performed best among those tested. Both of these have been tested previously in Poland in medium and long rotations. The data indicate the importance of testing cultivars under local climatic conditions before planting on a commercial scale.

“…Today such kind of farming covers thousands of hectares in Europe (Venendaal et al 1997, Langeveld et al 2012, with the most commonly grown species being willows (Salix) and poplars (Populus - Herve & Ceulemans 1996, Verwijst 2001, Langeveld et al 2012. This trend has also been accompanied by extensive plant breeding (Stanton et al 2010, Karp et al 2011), but the selection of new cultivars has been based almost entirely on inter-specific crosses. In Europe new poplar hybrids are derived mainly from crosses between P. nigra and P. deltoides Bart.…”

Such hybrids are capable of successfully pollinating and breeding with wild populations of P. nigra, and consequently are a threat to the genetic purity of this indigenous species (Cagelli & Lefèvre 1995, Benetka et al 2002, Smulders et al 2008.…”
