Tasting and smoking properties of tobacco products
depend on chemical composition of dried tobacco. The
most important are nicotine, carbohydrates, and
proteins. Their content is controlled when new sorts
are bred. In the article data on chemical composition
and their analysis for some hybrids, new and zoned
sorts are presented. Most of studied samples had
medium nicotine content in dried tobacco. Hybrid of
Jubileiniy noviy 142 and Ostrolist 46, sorts: Trapezond
159, 359, 115 and Ostrolist 46 were characterized as
low nicotine tobaccos. Jubileiniy (standard) and
Oktiabrskii were characterized as high nicotine
tobaccos. This indicator depends on rain quantity
during vegetation period. During drought seasons this
indicator is higher. Total soluble carbohydrates content
affects smoke taste. The more water soluble
carbohydrates content the better smoking properties
tobacco has. Unlike nicotine, carbohydrates content
when rainy season increases. Best results were for
Krupnolistniy 9M and Oktiabrskii. Proteins have
negative effect on smoke taste as it becomes bitter and
with smell of burned feathers. Most of studied hybrids
have quite high protein content. For cured tobacco
quality assessment, not total contents of proteins and
carbohydrates are important but their ratio
(carbohydrates/proteins) called Shmuk ratio. Best
results were for Krupnolistniy 9M and Oktiabrskii
Basic aim of institute’s breeding is to keep, renew and
increase selection and genetic resources of Nicotiana
tabacum. Final stages of this work are competitive and
state sort testing procedures. Their results are base for
zoning new sorts. In the article, the results on testing 8
new tobacco sorts of Trapezond and Ostrolist sort type
are presented. Testing on experimental field situated in
Severskii district of the Krasnodar region lasted for
five years. For this purpose, phenological observations,
biometric and technological properties measuring,
plant productivity and dried tobacco quality
assessments and other operations were carried. As the
result, Trapezond 25, Ostrolist 360 and Sheptalskii 63
sorts may be recommended for zoning and utilizing in
industry. Trapezond 25 and Sheptalskii 63 are sorts
with high productivity, high quality of dried tobacco
and good curing properties. Ostrolist 360 when earlymiddle
maturing keeps high productivity and quality of
cured tobacco. Other sorts: Trapezond 115, Ostrolist
311, Ostrolist 149, Ostrolist 90, Krupnolistniy 22 can
be initial material for further selection
