Characteristics of one-year-old shoots of peach hybrids from the crossing combination Flaminia × Hale Tardiva Spadoni

Abstract

The results of two-year research (2011-2012) of the most important morphological characteristics of 1-year-old shoots in eight peach hybrids obtained from a crossing combination Flaminia ? Hale Tardiva Spadoni were shown in this paper. The following characteristics were studied in tested hybrids: length and diameter of shoots, internode length, number of flowers and vegetative buds per shoot, ratio of flower to vegetative buds, number of flower buds per node and 1-m length of a shoot. The properties of sylleptic shoots on one-year-old shoots have also been studied. The significant differences were determined among the hybrids for parameters such as the diameter of shoots, internode length, number of flower and vegetative buds per shoot. Hybrids FH1 and FH6 were characterized by the highest density of flower buds, so that they are singled out as potentially the most yielding. These hybrids may be of interest for growing in areas where there is a risk of frost and in the domain of breeding when creating new peach cultivars of high yield potential.
