Genetic and selective analysis of clonal seed plantation of Pseudotsuga Menziesii Franco in the Cis-Carpathia region
Journal Title: Лісівництво і агролісомеліорація - Year 2013, Vol 123, Issue
Abstract
The results of the study of flowering and seed production of transplants of Pseudotsuga Menziesii Franco at a clonal seed orchard (CSO) in the Cis-Carpathia region are presented. Fertility of clones and their quantitative genetic parameters were determined, namely: average number of micro- and maсrostrobili on clone, sibling coefficient (ψ), group coancestry (Θ), effective number of parents (Np), relative effective number of parents (Nr), expected inbreeding (F). A simulation study (modeling) of effects resulting from various economic activities at the CSP was carried out, namely, creating a batch of seeds from the same number of cones of each clone and removing the clones with the least intensity of female “flowering” from the plantation. The expected genetic variability of seeds at the CSP based on the assessments of “flowering” of clones was calculated. Some loss of genetic variability (ΔGD) is expected in the progeny of there seed orchards CNR, due, among other causes, to low initial number of clones. In 2012 productivity of transplants at the plantation in terms of clones was determined. Quantitative and qualitative characteristics of plantation cones and seeds are presented. Measures for ordering and management of the CSP of Pseudotsuga Menziesii Franco were proposed.

Occurrence and peculiarities of tree colonization by stem pests in pine stands weakened by different factors in the forest-steppe part of Kharkiv region
Six species of invasive stem insect species in pine plantations in the region were detected. Tomicus piniperda L. (39%) dominated in the focus of the root rot, Ips sexdentatus Boern. (47.3%) and Tomicus minor Hart. (41.2...
