The study of the behavior in the pollination process of some local cherry populations

Abstract

The analysis of local cherry varieties both phenotypically and genotypically provides extremely important information for breeders. On the other hand, the valorization of some local, Romanian cherry varieties or local populations and their reconsideration in the breeding programs, constitute an important premise on the scale of adaptability to the local climatic conditions. In the pollination schemes were used local cherry populations from Ialomița, “Mari de Malu”, „Roșu de Mai” and the „Mărgărit” genotype that were hybridized with pollen from the Romanian varieties „Maria” and „Alex”. Although a considerable number of flowers have been pollinated, the binding rate still low between 7.33% and 10%. It is therefore observed how the exogenous pollen coming from the varieties partner in the pollination process positively influences the characters of the hybrid fruit, as it is not identical with the varieties used as parents. The statistical analysis of the results demonstrated that the native varieties of cherry constitute an extremely valuable potential in inducing some characters of resistance to diseases, productivity, quality, but also the fact that most of them are self-fertile.
