CHEMICAL COMPOSITION COMPARISON OF DRIED TOBACCOS OBTAINED FROM DIFFERENT HYBRIDS, SORTS AND LINES

abstract 1281704068 issue 128 pp. 1003 – 1013 28.04.2017 ru 394
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

FINAL INDICATORS OF VALUABLE PROPERTIES FOR NEW TOBACCO SORTS (FOR FIVE YEAR PERIOD)

abstract 1281704091 issue 128 pp. 1294 – 1308 28.04.2017 ru 399
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
