DYULGERSKI, Y., Тz. RADUKOVA and St. KIRKOVA, 2015. Biological and economic assessment of new lines Burley tobacco. Bulg. J. Agric. Sci., 21: 1211–1215
Examined are the biological and economic parameters of seven newly created lines of burley tobacco. Research results show that with the best biological assessment presents Line 1468, followed by a line 1472. Line 1468 gives the highest yield per hectare as an average over the period of study and three years of study. It also exhibited stability in terms of yield. Line 1488 gives the highest percentage of first class, as average for the period of study and for the three years of study. Therefore, no high yield which is obtained from it can essentially be used in breeding programs, as a donor of a high quality. All new created lines strongly outweigh the testimony of the standard variety, both in terms of production and in terms of percentage of class, which is an indication of the success of the selection work. Because shown favorable complex of biological and economic indicators Line 1468 should be proposed for production testing and for recognition as a new variety of Burley tobacco.
