Vectors of Efficiency in Hybrid Poplar Genotype Testing Silvae Genet. (IF 1.0) Pub Date : 2021-01-01 Neil D. Nelson,William E. Berguson,Bernard G. McMahon,Meijun Cai,Daniel J. Buchman
Abstract The Natural Resources Research Institute Hybrid Poplar Program breeds and tests genetically improved clones for bio-mass production and environmental services. The testing process progresses from Nursery Progeny Tests (NPT) to Family Field Trials (FFT) to Clone Trials (CT) to Yield Blocks (YB), with limited replication of many clones in FFT and CT and a limited number of highly selected clones

Genetic structure and postglacial recolonization of Pinus sibirica Du Tour in the West Siberian Plain, inferred from nuclear microsatellite markers Silvae Genet. (IF 1.0) Pub Date : 2021-01-01 D. N. Shuvaev,A. A. Ibe
Abstract The total of 257 trees from the ten natural Siberian stone pine populations of West Siberian Plain, Ural Mountains and Kuznetsk Alatau were studied with the eight nuclear microsatellite loci. Differentiation of population groups indicates the possible existence of separate refugia in the past in the Urals and Kuznetsk Alatau. The northern populations of Western Siberia were characterized by

Towards new seed orchard designs in Germany – A review Silvae Genet. (IF 1.0) Pub Date : 2021-01-01 Heike Liesebach,Katharina Liepe,Cornelia Bäucker
Abstract New first and 1.5 generation seed orchards are to be created in Germany based on recently assembled breeding populations of Acer pseudoplatanus, Larix sp., Picea abies, Pinus sylvestris, Pseudotsuga menziesii, and Quercus sp. To justify the high expenses in time and cost for orchard establishment and maintenance, planning should make use of consolidated knowledge and experience of both the

Genetic comparison of planted and natural Quercus robur stands in Russia Silvae Genet. (IF 1.0) Pub Date : 2021-01-01 Bernd Degen, Yulai Yanbaev, Celine Blanc-Jolivet, Ruslan Ianbaev, Svetlana Bakhtina, Malte Mader
Abstract Genetic diversity and the optimal genetic composition are essential for the adaptability and adaptation of tree populations. Artificial regeneration of stands might reduce the genetic diversity and increase family structures if the seeds were collected from a limited number of mother trees. We did a genetic inventory in 12 pedunculate oak stands in Russia using a set of 366 nuclear gene markers

Recent clonal reproduction of Cryptomeria japonica in a snowy region revealed by a survey of small-sized ramets Silvae Genet. (IF 1.0) Pub Date : 2020-12-17 Megumi K. Kimura, Takashi Nagashima, Tomohiko Kamitani, Hitoshi Sakio, Yoshihiko Tsumura
Clonal reproduction may contribute to population maintenance in areas where disturbance caused by snow limits tree recruitment. To understand the importance of clonal reproduction in the population dynamics of canopy tree species, it is necessary to determine the frequency of clonal reproduction in the early stages of seedling establishment. We found 106 ramets, including “small-sized” ramets of less

Genetic diversity of marginal populations of Populus euphratica Oliv. from highly fragmented river ecosystems Silvae Genet. (IF 1.0) Pub Date : 2020-12-17 Çiğdem Kansu, Zeki Kaya
Populus euphratica Oliv. (Euphrates poplar) is one of the naturally distributed poplar species and limited to south and southwestern Turkey. The species possesses great importance for both renewable energy resources and persistence of a healthy river ecosystem. Due to increased habitat destructions and fragmentation by human activities, the distribution area of this species has become narrower. Hence

Clonal variation in phenological synchronization and cone production in a Pinus patula seed orchard Silvae Genet. (IF 1.0) Pub Date : 2020-11-18 Liliana Muñoz-Gutiérrez, J. Jesús Vargas-Hernández, Javier López-Upton, Carlos Ramírez-Herrera, Marcos Jiménez-Casas
Synchronization between female receptiveness and pollen dispersal, and fecundity of clones influence effective population size and genetic diversity of germplasm produced in seed orchards. Our objective was to determine clonal variation in phenological synchronization and in cone production in a Pinus patula seed orchard. Two-year phenology data of female and male strobili from a sample of 31 clones

Effect of witches’ broom mutation on growth of Pinus sibirica seedlings Silvae Genet. (IF 1.0) Pub Date : 2020-11-06 Galina V. Vasilyeva, Evgeniya A. Zhuk, Sergey N. Goroshkevich
Mutational witches’ brooms (WB) spontaneously arise in the tree crown. There are no male cones in Pinus sibirica WB and pollination always occurs with normal pollen. We studied 2-year-old seed progeny obtained from open-pollinated cones of WB and normal crown (NC) pines. There were significant morphological differences in two pairs of WB and NC families, while the third family pair studied showed barely
