| Abstract:
The aim of this research was to determine genetic values for the number and weight of fruits in F1 and F2 generation of diallely crossed pepper genotypes, and to evaluate the effects of applying the pedigree and bulk breeding method for producing F3 hybrid populations. Hybrid populations were formed by crossing divergent genotypes belonging to different cultivars of species Capsicum annuum L. The research of parent lines lasted for three years, experiments with F1 generation for two years, while the analysis of results for F3 hybrid population has been done regarding the data from one year experiment. The heterosis effect in F1 generation for all researched traits and in all crossing combinations was very low. Genetic analysis of F2 generation showed that all researched traits were inherited with partial domination. In F3 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. | |
