Nowadays we are witnessing continuous spread of drought as a result of global warming. The need for irrigation
increases for all crops, including tobacco. The oriental sun-cured tobacco does not require large amounts of water,
but for obtaining a good quality raw material it is necessary to have some precipitation during the growing season. The lack of rain and irrigation water can be overcome by selection of varieties tolerant to drought. Tobacco Institute - Prilep has developed programs for investigation of the assortment and improvement of the existing varieties and creation of new genotypes. The investigation included nine varieties belonging to different types of tobacco, some of which are commercially used in the Republic of Macedonia and some are kept for further breeding. The trial was set up in the Experimental field of the Institute during 2012 and 2013 in randomized blocks with three replications.
The aim of the paper was to study the oriental varieties in order to obtain data on their tolerance to drought and to supply material for further selection. Drought tolerance was determined by classical breeding methods based on phenotypic expression of morphological and production traits. For this purpose, modern breeding programs are using molecular markers in different stages of the selection process. The highest degree of tolerance to drought was observed in genotypes P - 84 (type Prilep) and P - 2 (type Dzebel). These genotypes can be included in the programs for improvement of the investigated trait.
