Özet
Spheroid scots pine (Pinus sylvestris L. var. compacta (Tosun) U. Akkemik) clonal seed orchard was established in April 2004 including 823 ramets of 26 clones at 5m x 5m spacing in Eflani of Karabuk, Turkey. Five ramets per clone were chosen randomly and all of the male strobili over the entire crown on all grafts were counted in 2016 and 2017. Average numbers of male strobili per clone were ranged from 130.0 to 83710.7 for two consecutive years. Pearson correlation for two consecutive years on male strobili production was 0.91 showing stability 2016 and 2017. The top 25% of clones produced 48% of total male strobili in two years. Male fertility variation, effective status number and relative status number were 1.56, 16.61 and 0.64, respectively. Estimation of broad sense heritability and clonal coefficient of genetic variation for male production was 0.49 and 12% respectively. The parameters were discussed for management of Spheroid scots pine clonal seed orchard aiming ex situ gene conservation and landscape activities.
