“…Uslu and Bilir (2020) stated that the species outperformed pyramidal cypress in seedling height and diameter at root collar. Regarding the knowledge and general information on the cypress, some prominent studies include: Farahmand (2020), on genetic-breeding studies; Korol et al (1997), Capuana et al (2000), Papageorgiou et al (2005), Gallis et al (2007), Al-Hawija et al (2014, Nocetti et al (2017), Bagnoli et al (2020), andIsmael et al (2021).…”

In this study, the genetic and phenotypic relations among tree height, diameter at breast height and survival at 18 years of age were investigated in Mediterranean cypress (Cupressus sempervirens L. var. horizontalis (Mill.) Gordon) provenance-progeny trials established in two locations in southern Türkiye. It was found that the variation among families within one provenance was higher than among different provenances. At the joint analysis, the narrow-sense heritability (hi2) was 0.36 for height, and 0.24 for diameter. Family mean heritability (hf2) was 0.78 for height, while it was 0.53 for diameter. Diameter showed higher (13.98%) genetic diversity than height (12.71%). Genetic correlation between traits was high (0.84). According to the breeding values of the families estimated by the BLUP method, when the best 50 families by two traits are selected separately, 12.5% genetic gain in terms of height and 13.2% in terms of diameter can be achieved. In the selection of the best 30 families, the estimated genetic gain calculated was 15.2% for height and 16.3% for diameter.

“…A cypress breeding program conducted in Italy by IPSP-CNR has been mainly based on the evaluation of clones in experimental plots. The use of clones, obtained via vegetative propagation (grafting), allows the replication of selected traits, such as resistance to cypress canker disease, habitus, and growth, which are important for ornamental purposes, for the production of wood, and for windbreaks ( Raddi and Panconesi, 1991 ; Danti et al., 2006 ; Danti et al., 2013 ; Nocetti et al., 2015 ; Nocetti et al., 2017 ). The use of clones allows for more accurate evaluation of G×E interaction and genotypic stability compared to the use of seed progenies ( Bentzer et al., 1988 ).…”

Genotypic and environmental effect on male flower production in Cupressus sempervirens clones and selection of genotypes with reduced pollen emission

et al. 2022

Common cypress (Cupressus sempervirens L.) is widespread in the Mediterranean area and is frequently planted as ornamental tree in parks and gardens. Like other species of Cupressus, common cypress releases a significant amount of the total annual airborne pollen in most regions and is known as responsible for winter pollinosis. Although variation in the production and release of pollen has been observed among C. sempervirens trees growing in urban areas, no information is available on effects due to genotype × environment interaction on this trait. In this study more than 150 C. sempervirens clones were analyzed for two to four consecutive years in clonal orchards situated in central Italy to evaluate variations in the production of male cones. Variance component ANOVA underscored an important genetic control of male flowering, with high repeatability (from 0.80 to 0.95) found in single environments. Analysis for combined sites or years (in a single site) showed significant effect of environment and genotype × environment interaction on the total variance. Intra-trait genetic correlations between environments were moderate to high (from 0.40 to 0.92), which indicates that male cone production of clones is fairly consistent across years and sites. Of the 10 clones characterized by the lowest mean male cone production, three showed good stability across environments based on the linear regression coefficient and Wricke’s ecovalence. The mean cone production of these 10 clones was 5 to 10 times lower than the mean production observed in the same environment. These clones have both ornamental and hypoallergenic traits and hold promise for designing green spaces with low allergy impact.
