As a result of tobacco samples collection research, the 25 samples or 16.7 % of the studied material were included to the variety type Virginia. The optimum plant height (153-187 cm) was shown in 5 samples: 50 Varmor, Virginia 401, Virginia 15, C - Canada, White Gold. The best in leaves size (length 38 - 50 cm, width 18-25 cm) were also 5 samples: Varmor 50, Virginia 401, Virginia 15, C - Canada, Hevesy H – 6. It was identified 5 samples by the biometric indicators: Varmor 50, Virginia 401, Virginia 15, Hevesy H – 6, Many-sheeted 55. It was found 3 varieties that exceed the standard by 0.01 t/ha (Vamor 5), 0.25 t/ha (Virginia 15) and 0.36 t/ha (Virginia 401) by the raw materials yield level. Their yield level in the three-years average was 2.21, 2.45 and 2.56 t/ha respectively and the average yield of standard variety Virginia 27 was 2.2 t/ha.
The Virginia 401 and Vamor 50 varieties were characterized by high quality. The average output of higher commodity varieties was 85 % and 84 % respectively that is 5 % and 4 % higher than the standard variety data. The Virginia 84 (81 %) and Virginia 15 (81 %) varieties data were 1 % higher than standard variety data by the raw material quality.
It was revealed tobacco varieties that were connected by valuable economic and biological characteristics. So, the varieties Virginia 15, Virginia 401 and Vamor 50 combined high yield with the leaves size, biometric indicators and quality.
The 25 tobacco varieties, which were identified among the 150 collection samples and were match to Virginia sort type performance, were studied by breeding value. Their characteristic was given and the collection of Ukrainian Plant Genetic Resources Bank was replenished with valuable sources. The best of identified varieties were recommended for using in tobacco breeding programs as original material for the new varieties creation in the Transnistrian region of Ukraine.
