Dioryctria sp. Zeller 1846 damage in the point of clonal variation in Tekcam scots pine seed orchard in Kastamonu Taskopru

Abstract : This study has been carried out Kastamonu Taşköprü Tekçam seeds garden and 30 clones of cone and seed characteristics were determined. Dioryctria sp. which is cone and seed pest has been identified in the seed orchard. Dioryctri spp. are the potential pests in seed orchards. In this study, deformations on cones examined in six classes including 5 deformation class and control. According to the results, significant differences between the characteristics of cones and seeds are determined. According to the results the most resistant clone is No.9, most sensitive clone is No.12 clone in 2nd deformation class, the most resistant clone is No.21, the most sensitive clone is No.3 in 4th deformation class. The evaluation of significance could not be done because of sufficient seed in other deformation class (1,3,5). In case of all ramet cone having with class 2 deformation level, 834,35 kg of seeds can be harvested in the seed orchard garden, and with class 4 deformation level, 415,29 kg kg of seeds can be harvested. In case of all ramet cone having without any deformation level 1178,78 kg of seeds can be harvested in the seed orchard garden. In case of all ramet cone having with pests class 2 level causes %29,22 loss, and with class 2 level causes%64,77 loss.
