Purpose of research - to take into account in breeding process the productivity of inflorescence, which depends on the morpho-biological features of tobacco varieties, soil and climatic factors. Method of research - phenological observations were carried out according to the classifier Semenova. Certified was checked by DSTU 4138 and by the method of determining the similarities and control of varietal purity. Effect of various environmental factors on breeding patterns in the vegetation period was determined by their economic-value features according to the method Psareva. Results of research - optimized principle of selection and scheme of primary seedgrowing with different ripening. Determined optimum plant forms by the main morphological and biological characteristics, combining high performance as vegetative and generative organs. Scope - scientific research and breeding.
