Abstract: An assessment is made the biological, economical and chemical indicators of ten samples Burley tobacco, from which eight new promising lines, standard Pliska 2002 variety and Burley 1317 variety. As a result, the study found that that the most favorable biometric indicators are presented in Line 1506 and Line 1527. With the short vegetative period is characterized Line 1522, and the longest – standard Pliska 2002 variety. All new selection lines excel at length of the vegetative period standard Pliska 2002 variety. The highest yield was represented by Hybrid 1470, followed by Hybrid 1449. The highest percentage of first class is derived from Hybrid 1482, which gives the lowest percentage of third class. With favorable ratio of classes are formed Hybrid 1470 and Hybrid 1449. All new lines superior the standard variety Pliska 2002, to as yield, so and percentage of first class. With the most well-balanced chemical composition is Hybrid 1482. Generally, all new lines strongly outperform standard Pliska 2002 variety and to a lesser extent Burley 1317 variety. Complex assessment of biological, economic and chemical indicators shows that with the best parameters differs Hybrid 1470, and work with it will continue with production testing. Hybrid 1482 Hybrid 1469 and especially Hybrid 1449 are also emerging as promising.
