CHARACTERISTICS OF THE NEWLY CREATED GENOTYPE OF VIRGINIA TOBACCO LINE V79/09 CMS F1 IN THE REGION OF PRILEP DURING 2012-2016

Abstract

V-79/09 CMS F1 is a hybrid male sterile line created in the Scientific Tobacco Institute - Prilep in 2009 by intervariety hybridization. It was included in comparative trials in the period 2012/2016, performed at the Experimental field of the Tobacco Institute, along with introduced varieties as a check. Through the whole period of investigation, line V-79/09 CMS F1 showed better biomorphological and productional properties compared to the check varieties. Due to its characteristics, it surpassed all other varieties and lines included in the investigation. Thus, the line starts to flower in 71.8 days, 50% flowering occurs in 76.6 days and end of flowering in 81.8 days from the date of planting. The average length and width of the 5th leaf are 52.1 cm and 36.8 cm, of the 10th leaf 69.3 cm and 39.9 cm, and of the 15th leaf 64.7 cm and 35.1 cm, respectively. Height of the stalk with inflorescence averages 213 cm and the number of leaves is 34.0. The yield was 3450 kg/ha, but it should be mentioned that throughout investigation, the line V-79/09 CMS F1 showed statistically significant differences compared to the check varieties. All these characteristics make this line interesting for tobacco industry.
