Abstract

Purpose. To determine morphological and morphometric features of vegetative and generative organs of Persica species and varieties under the conditions of the Forest-Steppe zone of Ukraine for further use in breeding.

Methods. Biological (morphological analysis) and statistical (processing of morphometric parameters) ones.

Results. It was found that except ternate multiple buds, in peach hybrid ‘Suputnyk’collateral buds were prevalent which was not common to other tested varieties and species. Buds of each species and variety have a certain number of scales. The most scales were observed in ‘Suputnyk’. Pubescence of abaxial side of the leaf in P. davіdiana and ‘Suputnyk’ plants was not revealed. Species of P. vulgaris (‘Pecherskyi’, ‘Antotsianovyi’, ‘Poleskyi’) was characterized by increase in size of leaf blades, flowers and fruits. The distinctive features of P. davidiana and ‘Suputnyk’ are that stamens were accumulated in their flowers while in P. vulgaris they are branched. Raphe of a P. vulgaris stone protrudes above the edges of the bordering creases and consists of a number of narrow plates.

Conclusions. For the breeding purposes, plants have an advantage for some basic criteria: the most flower buds that is common to interspecies hybrid ‘Suputnyk’; increase in photosynthetic productivity of the leaf apparatus to be typical for the variety ‘Pecherskyi’; large fruits that ‘Pecherskyi’ variety is noted for; intense red color of fruits that is inherent feature of ‘Antocianovyi’ variety.
