dc.description.abstractThe international network of provenance and progeny trials was established in 1998 in France, Italy, Portugal, Spain and Tunisia under the EU Commission financed concerted action FAIR 202 benefiting from homogeneous plant raising and standardize experimental design. The trials include 34 provenances that are being characterised using quantitative genetics and molecular genetics to study survival, growth, morphological and physiological traits in relation with geographical origin. France 2008– Provenance were assess using survival, growth (height) and vigour parameters. Provenance PT 23 and PT+ES 25 had the lowest survival rate respectively 79,2% and 77,8% while ES 8, ES 7, MA 31 and PT 19 had 94,4%. In 2008 the mean height at Les Maures was 48.73 cm and the form keeps plagiotropic. Italy- Sardinia, Grighine, 2010 The average mortality was 7%, ranging from 13-14% at the provenance IT LA-VT; IT SI-CT; MO I-1 and 0-2% for FRII, ES 3-V, ES F-PAR, PT IV-03, TU I; TU II. Mean height and trunk DBH over cork were respectively 273cm and 5.1cm. MO I-2, TU II, ES 4-CR are above mean on height (302-309 cm), and the Italian provenances are under mean (237-249cm). The maximum DBH was reached by MO I-2 (6 cm) followed by ES-4 CR and MO III-2 (5.8 cm) and the minimum is at IT PU-BR (3.8 cm), followed by the other Italian provenances (4-4.6cm) and PT V-01 (4.5 cm). Portugal Results from field trials show significant differences among populations on survival, growth and adaptive traits (phenology, water use efficiency - WUE). Mogadouro trial, 2011 -provenance variation was assessed using growth, vigour and survival. The bud burst as adaptive characteristic was observed during 2011-2013. The Moroccan provenances show good adaptive characteristics in terms of growth, vigour and stem form. There was no significant differences (p<0.05) in provenances bud burst. The mean height is not correlated with survival. Italian provenances present lower height but higher survival. The overall mortality is around 26%. The highest growth is being observed in the Moroccan provenances and French ones showed lowest survival. Results from field trials at Italy (continent), Spain and Tunisia are also referred. Genotype by environment interaction (G x E) is discussed. Due to the large variability of responses between cork oak provenances we emphasise the importance to use these results when considering the seed origin aiming for large scale planting programs for adaptation, cork quality, pest and diseases susceptibility and for conservation of genetic resources, Progeny trials provide key information for genetic improvement programmes on estimates of breeding values on economic characteristics such as cork quality and an approach on inbreeding problems. Perspectives Used in synergy the results from provenance and progeny trials are likely to provide insights for balancing the conflicting objectives such as maximising selection intensity while maintaining variation. Taking into consideration that the cork from the second striping made 3-4 years after the first gives information about the quality liable to be used on selection for afforestation guide lines we enhance the need of concerted criteria on debarking season and procedures. The results from these trials will contribute to the knowledge on genetic variation and are a privileged living material to study climate change effects and adaptation to biotic and abiotic factors and for sustainable management of this long living species.pt_PT
