Vujosevic (2011): Influence of parental germplasm for fruit characters in F-1, F-2 and F-3 generations of pepper (Capsicum annuum L.). - Genetika, Vol 43, No. 2, 209 -216. The aim of this research was to determine genetic values for the fruit width and fruit length in F-1 and F-2 generation of diallely crossed pepper genotypes, and to evaluate the effects of applying the pedigree and bulk breeding method for producing F-3 hybrid populations. Hybrid populations were formed by crossing divergent genotypes belonging to different varieties of species Capsicum annuum L. The research of parental lines lasted for three years, experiments with F-1 generation two years, while the analysis of results for F-3 hybrid population has been done regarding the data from one year experiment. The heterosis effect in F-1 generation for all researched traits and in all crossing combinations was very low. Genetic analysis of F-2 generation showed that all researched traits were inherited with partial domination. In F-3 generation, hybrid populations formed by using the pedigree method of selection had traits which are more valuable for further breeding than the hybrid population formed by using modified bulk method.
