Abstract

Goal. Conservation of existing genetic material of tobacco, introduction of new Ukrainian and foreign tobacco accessions, the study on valuable traits complex, registration in the NCPGRU valuable accessions and the creation of the tobacco trait collection in Transnistria Ukraine conditions.Results and discussion.The article discusses the studing, preservation and using of tobacco varieties collection in breeding process. The main valuable quantitative and qualitative characteristics: yield, raw materials quality, plant height, leaf length and width, the leaf blade materiality were identified. The collection for economic valuable traits, which included 32 accessions from 8 countries (Ukraine, Russia, Moldova, USA, Canada, France, Yugoslavia and Switzerland) was created on basis of accessions. It has been identified 13 samples –standards with 42 occurrences of trait levels, selected sources of valuable economic traits, the implementation of which contributes to the effectiveness of breeding.Conclusions. According to the results of 2009-2013. 6 tobacco accessions with valuable traits were registered in the NCPGRU. The plant gene pool accession registration certificate in Ukraine was received for each of them: Burley variety 38, Macrophylla 4, Burley 46, Podolsky 23, Ternopil 14 and Macrophylla 45.
