The effect of parent's germplasm on yield components of F1, F2 and F3 generations of pepper hybrids (Capsicum annuum L.)

The aim of this research was to determine genetic values for the number and weight of fruits 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 cultivars of species Capsicum annuum L. The research of parent lines lasted for three years, experiments with F-1 generation for 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.
