“…In contradiction with this, Zhang et al (2013) noted correlation between genetic distance and geographic distance using RAPD and ISSR analyses in 15 individual samples of Larix gmelinii. In addition, Oreshkova et al (2013) found a significant correlation of the genetic distances with the geographic distances between Siberian larch, Gmelin larch, and Cajander larch populations based on SSR-marker data. On the other hand, studies regarding the European larch (Larix decidua) based on levels and patterns of allozyme variation proved that there was no statistically significant relationship between genetic and geographic distance (Lewandowski and Mejnartowicz, 1991).…”

decidua (European larch) has a scattered natural area and is present in four geographic zones (Alps, Sudetan Mountains, Carpathians, and Central Poland), where local European larch have sometimes the status of subspecies or varieties (Biswas and Mohri, 1997). In Romania, the larch has a natural range, being gathered into 5 genetic centers: Ceahlau Mountains (1400-1450 m altitude), Ciucas (1000-1450 m), Bucegi (1200-1500 m), Lotru Mountains (670-1900 m with a maximum range in this area), and Apuseni Mountains (600-1200 m), and in many other plantations more than 200,000 cultivated ha (Mihai and Teodosiu, 2009). The origin of seed is mostly unknown, but probably in the old plantation the seed has Austrian origin.Larch breeding objectives include growth, stem form (crookedness), branching, and resistance to larch canker. There is ongoing research for traits such as heartwood formation and quality (Plomion et al., 2001). Larch heartwood is appreciated for its good mechanical properties, its color, and its texture, and it is often used outdoors for its natural durability (Gierlinger et al., 2004).

“…Similar results are also reported in other studies of Larix spp. (Larionova et al 2004;Nishimura and Setoguchi 2011;Oreshkova et al 2013). However, when null alleles in our study were taken in account as proposed by Chybicki and Burczyk (2009), only a very small homozygote excess was observed.…”

“…Similar to Wagner (2013), in our study marker bcLK263 and bcLK211 had the highest and Ld42 had the lowest number of alleles. Comparisons with species within the genus Larix reveal higher microsatellite diversity for L. decidua (H e = 0.75) than for L. lyallii and L. occidentalis (0.42 and 0.58; Khasa et al 2006) as well as for L. gmelinii (0.41-0.60; Zhang et al 2015), L. sibirica, and L. cajanderi (0.63 and 0.56; Oreshkova et al 2013). H e estimates in L. kaempferi (0.72-0.76; Nishimura and Setoguchi 2011) are similar to our results.…”

& Key message Historic transfer of larch from Alpine sources to Southern and Eastern Carpathians has been verified by means of nuclear genetic markers. Tyrolean populations can be differentiated into a northwestern and southeastern group, while Romanian populations are separated according to the Southern and Eastern Carpathians. Low-level introgression from Alpine sources is found in autochthonous Carpathian populations. & Context Large scale human mediated transfer of forest reproductive material may have strongly modified the gene pool of European forests. Particularly in European larch, large quantities of seeds from Central Europe were used for plantations in Southern and Eastern Europe starting in the mid nineteenth century. & Aims Our main objective was to provide DNA marker based evidence for the anthropogenic transfer of Alpine larch reproductive material to native Carpathian populations. & Methods We studied and compared 12 populations (N = 771) of Larix decidua in the Alps (Austria, Italy) and in the Southern and Eastern Carpathians (Romania) using 13 microsatellites. & Results High genetic diversity (H e = 0.752; R S = 9.4) and a moderate genetic differentiation (F ST = 0.13; G′ ST = 0.28) among populations were found; Alpine and Carpathian populations were clearly separated by clustering methods. A Tyrolean origin of plant material was evident for one out of four adult Romanian populations. In the transferred population, a genetic influence from Carpathian sources was found neither in adults nor in juveniles, while the natural regeneration of two Romanian populations was genetically affected by Alpine sources to a minor degree (2.2 and 2.9% allochthonous individuals according to GeneClass and Structure, respectively). Handling editor: Bruno Fady Contribution of co-authors: Hannes Raffl did the sampling, lab work, computations, and statistics and leads the writing of the manuscript. Heino Konrad supported lab work, assisted in data analysis, took part in the discussion of the results, and provided input to the manuscript. Lucian Curtu was the local support in sampling in Romania, contributed to discussion and manuscript writing. Thomas Geburek conceived the study, supported the interpretation of the results, and provided input to the manuscript.

“…The analysed tree stand is characterised by a high gene diversity (number of alleles and expected heterozygosity of ~86%) compared to other studies which used the same or parts of the same markers (Babushkina et al, 2016;Oreshkova et al, 2013;Pluess, 2011). Nevertheless, we observe a heterozygote deficit, which results in significant deviations from Hardy-Weinberg equilibrium, even though the analysed trees grew in a large area (one hectare).…”
