Andreyeva V. Forestry selection estimation of half sibs and sibs progeny of Scotch Pine in the conditions of Western Polissya

Object of investigation is vegetative and seminal posterity of plus trees of Scotch pine. Goal of work - to study the variability of is vegetative and seminal posterities of Scotch pine in the conditions of Western Polissya on biometric indexes, to explore nucleolus descriptions of meristem and set methodical possibilities of genetic-selection estimation of plus trees and early diagnostic of growth posterities. Research methods: biometric, cytogenetic, genetic-selection, mathematical statistic. First in the conditions of Western Polissya genetic-selection estimation of plus trees of Scotch pine after morphmetric and cytogenetic indexes of vegetative and seminal posterities are presented. The comparative analysis of growth and selection structure of the same name half sibs families and candidates in the synthetic sort-populations the row of years and from different locations was carried out. We recommend candidates in sort-clones (27) and plus trees - candidates in elite. First for the plus trees of Scotch pine cytogenetic variability of nucleolus descriptions (number of nucleolus in a nucleus, their volumes, index of relation of total area of nucleolus in a nucleus to the area of cell) is explored and set influence of term of storage of seed on nucleolus activity. Coefficient of correlation between indexes of nucleolus activities of sprouts and growth indexes of plus trees and their posterities is high (r=0,9). We can use it for early diagnostic of growth.. Results: the obtained results will serve for refreshing of permanent seed-forest base of Scotch pine in Volyn region. Branch of application: forestry.
