Tereshchenko L. Intraspecific variability and sign's inheritance of Pinus sylvestris L. plus trees in Kharkiv region

The object is intraspecific variability of qualitative and quantitative indexes and regularities of its inheritance; the aim -studying of intraspecific variability of qualitative and quantitative indexes of Scots pine plus trees and revealing of its inheritance by progenies regularities; methods - biometrical, phenological, morphometrical, anathomical, mathematic-statistical; the new approach - first in the region the variability and display of hereditary peculiarities of Scots pine by the complex of indexes has studied, the coefficients of inheritance of the main growth and reproductive peculiarities was calculated; the main include - the characteristics of plus tree's clones and their progeny was increased and augmented; the using of Scots pine progeny early diagnostics method according to presence of shoot's secondary increment and their development was proposed; during establishment of a clonal seed orchards of second generations, besides using growth characteristics of progenies, it is necessary to take into consideration the clones characteristics by presence of anomalous pollen grains and pollen tubes growth peculiarities, cones and seeds biometric and qualitative indexes; the best trees in sib's families' was preliminary selected and their necessarity to use for clonal seed orchards establishment; clonal seed orchards and progeny tests (F1, F2) in Zmiev and Guty forest regional enterprises was established by author participation; the field is forest tree breeding and seed growing.
