In contrast to the cultivated type Nicotiana tabacum, which has haploid number of chromosomes (24), wild tobacco species differ in the number of chromosomes and in morphological properties also, such as: stalk, leaf number, flowers and plant height. Some wild tobaccos species have the same number of chromosomes as the cultivated tobacco and can be easily used for crossbreeding. This should be emphasized because the most important reasons for crossing are plant resistance to diseases and inheritance of some morphological traits, e.g. higher leaf number, shorter vegetation period, etc. The trial was set up in the experimental field of the Scientific Tobacco Institute – Prilep in 2014 and it included the following species: N. rustica, N. alata, N. longiflora, N. petunia hybrida, N. repanda, N. glutinosa, N. miarsii, N. undulate. The obtained results were compared with the standard variety P 12-2/1.
The aim of the study was to analyze some morphological traits (length, width and number of middle belt leaves) of tobaccos grown in the region of Prilep and to compare them with the cultivated species N. tabacum. Тhe results of the study will be of benefit to tobacco breeders. Data on morphological measurements were statistically processed using the following parameters: mean error of the average (сx̄), standard deviation (σ) and coefficient of variation CV%.
Key words: length, width, number of middle belt leaves
