New burley tobacco cultivars released in Romania

Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
After flue-cured tobacco, Burley tobacco occupies a significant place in tobacco production in Romania. Burley tobacco breeding, using germplasm from foreign cultivars and local Romanian lines, allowed for the selection of certain Romanian cultivars of Burley tobacco with high yields, good industrial and chemical quality of the cured tobacco, as well as resistance to PVY and TMV. The most valuable Burley tobacco cultivars were tested in a comparative field trial in two locations, one in the centre of Transylvania (Decea) and the other in the west (Biled - Banat), during the period 1999-2001. The new cultivars: Burley 190, Burley 191, Burley 194, Burley 196 and Burley 224 were compared with two controls: Burley 114 and Tennessee 86. The statistical analysis of the experimental results, in the soil and climatic conditions of the two areas indicated that: - the morphological and physical characteristics of the tobacco leaf are typical for this type; - the yield capacity of the cultivars varied between 2,300 - 2,800 kg/ha of cured tobacco, the best results being obtained from the cultivars Burley 194 and Burley 196; - the industrial quality of tobacco is very good, obtaining 86 - 92% cured tobacco for the classes I+II, particularly noticeable in the cultivars Burley 196 and Burley 191; - the chemical quality of the cured tobacco is within the limits of Burley tobacco; - the cultivars: Burley 114, Burley 196, Burley 194 and Burley 190, show double resistance to the most widespread viruses in Romania (TMV, PVY). This was tested using artificial inoculation.
