Abstract

Investigations were made on the inheritance of length, width and middle belt leaf area in progenies of six F1 and six F2 diallel crosses from four parental varieties (oriental Prilep P12-2/1, Pobeda P-2 and Yaka YV 125/3 and semi-oriental Forchheimer Ogrodowny - FO). Crossing was made in 2004 and 2005, and the trial with parents and hybrids was set up in 2006, in the field of Tobacco Institute-Prilep, at randomized block system with four replications. The aim of the investigations was to present a comprehensive picture on the genetic system of leaf size, through regression analysis. Values of the major genetic components required for graphic presentation were calculated from the average values of the investigated characters. The regression analysis reveals partially dominant mode of inheritance of leaf size and lack of interallelic interaction. According to the position of points along the regression line, there is higher number of dominant genes in P 12-2/1 and of recessive genes in P-2 for inheritance of leaf size in both generations. In YV 125/3 higher frequency of dominant genes was observed in F1 and of recessive genes in F2 for inheritance of leaf length; of recessive genes in F1 and dominant genes in F2 for leaf width; of dominant genes in F1 and equal number of dominant and recessive genes in F2 for inheritance of middle belt leaf area. In FO, higher frequency of dominant genes for inheritance of leaf length was observed in both generations, of recessive genes in F1 and dominant genes in F2 for leaf width and equal number of dominant and recessive genes in F1 and of recessive in F2 for inheritance of middle belt leaf area.
