Exploring New Varieties and Lines Oriental Tobacco the Region of Northern Bulgaria

Abstract

The study was conducted in the period 2011 – 2013 in Agricultural Experimental Facility Han Krum, Shumen municipality. We studied the morphological and economic qualities of new varieties and lines of oriental tobacco variety group Kabakoulak. There have been differences between the tested varieties and lines. There are forms with more leaves of a plant, the extent of which the lower and middle harvesting layers are smaller. The size of the leaves of the upper layers are proven positive differences from standard Han Tervel 39. These are positive trends in plant breeding from a varietal Kabakoulak. Studied lines have a shorter growing season than the standard and defined as early to medium early. Of them received higher quality raw material, but dry tobacco yield inferior standard.
