Abstract

Heterosis is a phenomenon in which hybrids in F1 progeny have better characteristics than their parents, with an increase in their vigor and yield. Its utilization means of the highly uniform varieties, i.e. hybrids with one-year application. Our investigations included the following quantitative characters: height stalk, number of leaves per stalk, length, width and area of the middle belt leaves, green and dry mass yield per stalk and nicotine content in four tobacco varieties (Prilep P 12-2/1, Pobeda P-2, Yaka YV 125/3 and Forchheimer Ogrodowni FO) and their six diallel F1 hybrids. Crosses were made in 2005 and in 2006 complete trial was set up in the field of Tobacco Institute-Prilep, using randomized blocks with four replications. The aim of investigations was to study the heterotic effect for the above mentioned characters in the progeny of F1 generation and possible application of this effect. The obtained results revealed positive heterosis in YV 125/3 x FO (for stalk height), P 12-2/1 x P-2 and P-2 x YV 125/3 (length, width and area of middle belt leaves), P 12-2/1 x P-2 (for green mass yield), P 122/1 x P-2 and P-2 x YV 125/3 (for dry mass yield) and YV 125/3 x FO (for inheritance of nicotine content). Negative heterosis was observed in P-2 x YV 12
