El programa de mejora genética gallego Pinus pinaster iniciado en los años 80 por el Centro Investigación Forestal Lourizán, actualmente está centrado principalmente la resistencia al nematodo Bursaphelechus xylophilus, patógeno presente España desde 2008. Entre diversos estudios realizados para determinar inclusión como carácter selección programa, se evaluó virulencia cepas distintos países, resultando ser cepa detectada Galicia 2010 una las más agresivas y, tanto, utilizada ensayos...
Pine wilt disease (PWD) is caused by the nematode Bursaphelenchus xylophilus, an invasive pest that currently constitutes greatest threat to pine forests worldwide. Breeding for resistance one of main strategies coping with this in most severely affected countries. This work evaluates genetic variation susceptibility B. xylophilus among 91 half-sib families from a Pinus pinaster breeding population was selected growth and stem form Galicia (NW Spain). We performed artificial inoculations on...
Cherry leaf spot (Blumeriella jaapii (Rehm) Arx.) is a very serious disease of wild cherry (Prunus avium L.), which produces premature defoliation and vigor decrease. In two clonal seed orchards P. naturally infected by B. jaapii, spatial heterogeneity autocorrelation neighbor damage caused impeded proper analysis the fungus incidence. The iterative (ISA), based on variography kriging, was successfully used to eliminate effect this in genetic variation susceptibility jaapii. Significant...
Full understanding and control of pine wilt disease (PWD) is a work in progress breeding for resistance constitutes an essential management strategy reducing its impact, as evidenced by advanced programs countries such Japan. Since Pinus radiata one the most commercially relevant species northern Spain, we designed study to assess genetic variation susceptibility this pathogen using 44 P. half-sib families from Galician program. Three Bursaphelenchus xylophilus (pinewood nematode, PWN)...
Flushing, spring frost damages and height were recorded in a provenance test including nineteen populations covering most Spanish chestnut distribution analysed to study the differentiation among wild populations. There was remarkable flushing time growth Qst higher for damage, lower height. The coefficients of quantitative similar values obtained other autochthonous species. classified three groups: early xeric from Mediterranean, late northern mountains intermediate Galician coast Canary...
Abstract Key message The resistance of Pinus pinaster Aiton to pinewood nematode Bursaphelenchus xylophilus (Steiner and Buhrer) varied among populations from the Iberian Peninsula, with survival rates for inoculated seedlings ranging 5 100%. These differences in were paralleled by some constitutive chemical defenses. Populations southeastern Peninsula displayed higher than northern populations. Context presence (PWN), Buhrer), Portugal threatens Mediterranean pine species such as Aiton....
Maritime pine (Pinus pinaster) is a forest species of great ecological and economic interest in the European Union, especially Iberian Peninsula. Currently, one main threats this has to face spread quarantine pathogenic fungus (A2 list) Fusarium circinatum, causal agent pitch canker disease. Since strategies for control disease use resistant clones, it necessary carry out extensive work on susceptibility analysis several P. pinaster populations against F. circinatum. To end, we have studied...
PREMISE OF THE STUDY: Plants have developed mechanisms to withstand stressful environmental conditions, but the high energetic cost of these may involve exchanges with other key functions. While trade‐offs between cold hardiness and growth rates are a general assumption, we lack information regarding genetically based life‐history traits. Such has strong implications for tree conservation breeding, especially in context ongoing climate change. METHODS: We used common garden progeny test...
Several traits of common walnut (Juglans regia L.) were assessed during the first three growing seasons in a progeny test 43 open-pollinated families at two sites northwestern Spain. Variance components, heritabilities and correlations between calculated for all characteristics measured. Significant differences found among with regard to growth, phenology, frost damage, number apical branches, Phytophthora cinnamomi Rands but not growth-habit (number stem form, dominance). Heritabilities...
Abstract Recent new outbreaks of Bursaphelenchus xylophilus in Spain and adverse pine wilt disease expansion forecasts must be met with rapid advances genetic breeding against this pathogen. The optimal approach for trees that are more resistant to is use the most virulent isolates inoculation assays. A series controlled experiments on Botrytis cinerea cultures, along Pinus pinaster P . radiata branch sections seedlings, was conducted investigate differences among seven B diverse geographic...
Abstract The contribution of genetic adaptation and plasticity to intraspecific phenotypic variability remains insufficiently studied in long‐lived plants, as well the relevance neutral versus adaptive processes determining such divergence. We examined importance phylogeographic structure climate modulating plastic changes their interdependence fitness‐related traits a widespread Mediterranean conifer ( Pinus pinaster ). Four marker‐based, previously defined classifications along with two ad...
Abstract In the present study we investigated reproductive phenology of Prunus avium in a seed orchard located northwestern Spain. The was carried out with 103 clones from 7 provenance regions northern most advanced flowering stage on different dates and number flowers cherries were monitored over two consecutive years. Significant differences among found for all studied traits, high broad-sense heritability estimates all, except duration synchronization index, both which showed moderate...
Four walnut tree species, of value for their wood production, were evaluated autumn cold resistance: Juglans regia L., nigra major Torr. A. Heller, and ×intermedia. Early frost events damage reduce quality lengthen timber harvesting rotation. The vulnerability these species could be an even more important problem in the future, depending on which Mediterranean climatic scenario develops. work is based use chlorophyll fluorescence parameter Fv/Fm—measured cortical bark chlorenchyma—as a...
Aim of the study: The Breeding Program wild cherry (Prunus avium) developed by Lourizán Forest Research Center (NW Spain), aims for creation Main Population, that is formed a large number plus trees and obtaining an Elite Population generated from controlled crosses selected by, at least, one trait economic importance. aim this study was to genotype 131 accessions Prunus avium trees, included in breeding program.Area are located North, Northwest Central Spain.Material Methods: were genotyped...
Different studies have emphasized the influence of resin canal traits in susceptibility pine trees to wood nematode (PWN) Bursaphelenchus xylophilus. Resin canals can facilitate PWN migration through stem and are involved accumulation volatile terpenes xylem response pathogen, inducing tracheid embolisms. In this work, we conducted a inoculation experiment under greenhouse conditions investigate anatomical constitutive among seven Pinus species with different degrees PWN: P. canariensis,...
