“…In southern Ontario (south of 448N latitude with T min > À12.8 8C and T a > 6.8 8C), the interspecific hybrids had competitive survival rates and often superior growth to P. strobus 20-43 years post-establishment (Table 3). These results agree with the reported heterosis between P. strobus and P. wallichiana (Kriebel, 1983), but also suggest that such heterosis might only be detectable when the interspecific hybrids had expressed their growth potential under favorable environmental conditions.…”

“…An alternative strategy in developing stronger genetic resistance to C. ribicola in P. strobus is to integrate resistance genes from Eurasian white pine species that have co-evolved with C. ribicola and demonstrate strong natural resistance to the pathogen (Heimburger, 1962(Heimburger, , 1972Bingham, 1972;Kriebel, 1983;Garrett, 1985;Zsuffa, 1985). In Ontario, Canada, interspecific hybrids of P. strobus and P. wallichiana A.B.…”

“…It should be stressed that in this progeny test, parental selection was random with regard to growth and for this reason heritability and consequently genetic gains are underestimated. A similar case was reported by KRIEBEL (1983) in eastern white pine (Pinus strobus L.). XIANG et al (2003b) reported that full-sib family selection in loblolly pine produced 40 % genetic gain over selection on half-sib families while CARSON (1986) reported that in radiata pine, the highest gain could be made by selection and controlled intermating of high g.c.a.…”

A full diallel mating design (10 parents) was carried out in a Swiss stone pine panmictic population from the Carpathian Mountains. At age six, after nursery testing, the progenies were field planted to one site, using a completely randomized block design with 100 families, four replicates and a 15 tree row-plot per replication, spaced 2.5 x 2.5 m. Total and annual height of all individuals of this test was assessed at successive ages, between ages eight and 16. In addition, weight of 100 seeds and cotyledon number were considered in correlation analyses. Significant differences occurred in total height for general and specific combining ability effects. Variance components, heritabilities, genetic correlations and genetic gains on growth traits and survival at age 16 were estimated. Across the field testing period, GCA 3) variance increased with time, accounting for 65 % of plot mean phenotypic variance by age 16. In contrast, SCA variance declined as the progeny test aged accounting for only 9 % by age 16. The time trend of the four heritability estimates for total height increased with age across the testing period reaching their highest level between age 14 and 16. Genetic correlations over time for total height rose from 0.85 at age two to 0.94 at age six and then leveled off across the field test indicating that if the goal is to improve 16-year height, early selection can be considered at age six. By selecting the best 10 %, 15 % and 20 % of individuals within the best fullsib families, a genetic gain in total height of 12.4 %, 11.0 % and 9.9 % respectively, could be achieved at age 16. A higher gain can be obtained if the best general combiner parents are selected and intermated.

“…Pinus peuce is often planted as an ornamental tree worldwide (Lines, 1985;Merrill et al, 1996;Mortenson & Mack, 2006). This pine hybridizes easily with P. strobus and P. monticola and usually produces abundant viable seed (Lu & Derbowka, 2009); therefore, it has been used in genetic trials to provide blister rust resistance to these white pine species (Kriebel, 1983;Blada, 2000;Sniezko et al, 2008). Few diseases and little related damage are reported for P. peuce in its native range (Lines, 1985); however, this pine from the Balkans appears highly susceptible to infection and damage from this needle blight.…”

An outbreak of Dooks needle blight (Lophophacidium dooksii) in a five-needle pine genetic archive containing nine five-needle pine species and their interspecific hybrids provided an opportunity to observe the differential susceptibility of these pine species to the disease. Survey results indicated that four of the nine species in the archive were susceptible, including new hosts western white pine (Pinus monticola) and Himalayan blue pine (P. wallichiana), as well as previously reported hosts eastern white pine (P. strobus) and Macedonian pine (P. peuce). Japanese white pine (P. parviflora) and Korean pine (P. koraiensis) were seemingly not affected by the pathogen. While P. peuce and its interspecific hybrids showed the highest susceptibility and the heaviest needle damage, P. parviflora and its interspecific hybrids, including those with P. peuce, were rarely infected, indicating a potential strong and dominant genetic resistance to the pathogen. Pinus monticola and P. strobus showed similar levels of susceptibility and needle damage. Implications of these results to forest health in North America and the Balkans are discussed.Résumé: Une éclosion de brûlure des aiguilles de Dook (Lophophacidium dooksii) dans un réservoir génétique de pins à cinq aiguilles contenant neuf espèces et leurs hybrides interspécifiques a fourni l'occasion d'observer la susceptibilité différentielle de ces espèces à la maladie. Les résultats de l'étude indiquent que quatre des neuf espèces du réservoir étaient réceptives à l'égard de la maladie, y compris de nouveaux hôtes comme le pin argenté (P. monticola) et le pin pleureur de l'Himalaya, et des hôtes préalablement signalés comme le pin blanc (P. strobus) et le pin de Macédoine (P. peuce). Le pin blanc du Japon (P. parviflora) et le pin de la Corée (P. Koraiensis) n'étaient apparemment pas touchés par l'agent pathogène. Tandis que P. peuce et ses hybrides interspécifiques affichaient le plus haut degré de réceptivité et les dommages les plus lourds causés aux aiguilles, P. parviflora et ses hybrides interspécifiques, y compris ceux créés avec P. peuce, étaient rarement infectés, indiquant une résistance génétique potentielle forte et dominante à l'agent pathogène. Pinus monticola et P. strobus ont affiché des degrés de réceptivité et des dommages aux aiguilles similaires. Nous discutons les implications de ces résultats sur la santé des forêts d'Amérique du Nord et des Balkans.
