Abstract

The paper presents investigations on the inheritance of length, width and area of middle belt leaf in oriental tobacco varieties Prilep (P0 10-3/2), Djebel (Pobeda P-2) and Yaka (YK 48), and the semi-oriental Forchheimer Ogrodowny - FO, including their six F1 and six F2 hybrids. Investigations and crosses were made in 2006 and 2007, and the final trial with parents and hybrids was set up in 2008, in the field of Scientific Tobacco Institute-Prilep, in randomized block system with four replications.
The aim of investigations was to present a comprehensive picture on the genetic system of inheritance of these characters by the use of graphic analysis.
Values of the major genetic components required for graphic presentation were calculated from the average values of the investigated characters, using the methods of Mather and Jinks (1974).
The regression graphs reveal partially dominant type of inheritance of the characters and absence of interallelic interaction. The position of points along the regression line reveals higher number of dominant genes in P 10-3/2 for inheritance of length, width and area of the middle belt leaves. P-2 variety has higher number of recessive genes. In YK 48 both dominant and additive genes are present, with small prevalence of ones over the others. In FO variety dominant genes prevail for inheritance of leaf length and width, and recssive genes for inheritance of middle belt leaf area.
Key words: tobacco (Nicotiana tabacum L.), inheritance, quantitative characters, graphic analysis
