INHERITANCE OF DEVELOPMENTAL PHASES OF VEGETATION PERIOD DURATION IN INTRASPECIFIC HYBRIDS OF HOPCHATNIK DEPENDING ON THE TYPE OF FRUIT BRANCHES
Journal Title: International scientific journal Science and Innovation - Year 2024, Vol 3, Issue 4
Abstract
The article presents the results of inheritance of duration of development phases depending on the type of fruit branches. It was found that the studied developmental phases in intraspecific and interspecific F1 hybrids by duration of vegetation periods "sowing-flowering", "flowering-ripening" and "sowing-ripening" have different genetic nature of inheritance, i.e. intermediate inheritance, dominance and overdominance in the direction of soon-ripening and late-ripening parent. In F2 hybrids with marginal and non-marginal branching type, the inheritance of developmental phases is similar to F1 hybrids, although in most cases, late maturity is inherited by dominance and overdominance. The type of fruiting branches is not significant in the inheritance of developmental phases. It should be noted that the studied developmental phases are complex polymeric traits, and their inheritance depends on the combinatory ability of parental forms.
