Study On The Most Important Morphological And Agronomic Characteristics Of Oriental Tobacco Genotypes

Abstract

From an experiment with 30 lines and varieties, five oriental tobacco genotypes (four newly created lines and one standard variety) were selected and examined for: stalk height with and without inflorescence, number of leaves per stalk, length, width and leaf area from the middle beld of the stalk and yield of dry leaf mass per stalk, dekar and hectare. The trial was set up in the Experimental Field of Scientific Tobacco Institute – Prilep in 2022 and 2023, in randomized block design with four replications, using traditional agricultural practices. Measurements of the morphological characteristics were made at the stage of butonization and beginning of flowering. The yield of dry leaf mass was determined during the treatment of cured tobacco. The results were statistically processed. The aim of the research is to study the more important quantitative characteristics of the oriental genotypes, to determine the degree of uniformity of the populations through their variability and to emphasize the best among the selected assortment. From the analysis of the results obtained from the comparative experiment, it can be concluded that the lines Lc and L-d are high-yielding, phenotypically and genotypically uniform and stable, thus granting a visa for their recognition as varieties by the Variety Commission from the Ministry of Agriculture, Forestry and Water management of the Republic of North Macedonia
