Abstract

Six parental genotypes (P-23, MB-3, SM-1, YV 125/3, FL-5 and O-87) and their 15 diallel hybrids in F1 and F2 generations were investigated for two characters, stalk height without inflorescence and leaf number per stalk. Field trials were set up in Tobacco Institute-Prilep in 2008 and 2009 in a randomized block design with four replications. Standard agrotechnics was applied in tobacco growing. The aim of investigations was to estimate the variability of characters using the basic statistical parameters standard deviation and degree of variability. Parents and F1 generation showed a very low variability, which indicates a high level of uniformity. In F2 progeny high variability was estimated, indicating the existence of differences among individuals and higher possibility of choice for the breeders. The highest variability in F2 for these two characters in both investigating years was estimated in the hybrids P-23 x O-87 and P-23 x FL-5.
