EX SITU CONSERVATION OF ENGLISH OAK OLD-GROWTH TREES GENE POOL

The possibility of English oak old trees gene pools conservation in ex situ conditions and the prospects for their using in tree improvement research were considered in the article. During selection of the first plus trees in Ukraine in the 50s of the last century were involved in several English oak trees in age of 200-300 years, which were later excluded from the State Register of plus trees, but their progeny remained in the progeny test plot created in 1958, and clones – in clonal seed orchards created in 1979 by N. I. Davydova in the left?bank forest-steppe of Ukraine. The analysis of old oak trees progeny growth and development in the progeny test and their clones in the clonal seed orchards are represented. It was proposed to a clonal archive and their progeny test creations by of the gene pool of old oak trees conservation and reproduction.
