EXAMINATION AND ANALYSIS OF YIELD, QUALITY AND ECONOMIC EFFECT WITHIN VARIETES OF BURLEY TOBACCO

The fact that there is no ideal variety created once and for all, but that some variety at a given moment is better than the others, motivated the breeders of Tobacco Institute - Prilep to create new varieties (genotypes) with improved characters, i.e. with higher yields and quality. Since these characters are governed by the genetic structure, parents in which these characters are predominant are used in the process of hybridization. According to the above data, the highest average yield per stalk of 200,5 g was recorded in the F1 hybrid B-204/15. Topping of the inflorescence, combined with sucker control in Burley tobacco can result in 28% yield increase per hectare (Berenji and Nikolič, 1996) According to the data presented in Table 2, the highest average yield per hectare of 4 477 kg was recorded in the variety B-204/15, which is 1 874 kg (72,55%) higher compared to the check variety L-8, which average yield was 2 583 kg/ha. According to the above data, the highest average gross income of 4 512 US$/ha was recorded in the hybrid B-204/15, which is 2 455 US$/ha, i.e. 119% higher than the check variety L-8, which achieved 2 057 US$/ha.
