Abstract
Abstract Genetic relationships of black-fruit hawthorns of the Carpathian basin have been investigated based on intergenic cpDNA sequences; first of all of the endemic Crataegus nigra and related species. Considerable infraspecific variation was detected in the East Asian taxon C. chlorosarca and some divergence in the Eurasian C. pentagyna. Based on the genetic analysis of investigated and reference psbA-trnH sequences, classification of sections Crataegus and Sanguineae is highly supported. From the studied taxa, C. pentagyna and C. monogyna was ordered to Sectio Crataegus, while C. nigra and .C. chlorosarca to Sectio Sanguineae. Based on our data, C. nigra can be considered as maternal parent of the investigated C. × degenii hybrids. Kivonat Három kiválasztott “fekete termésű” galagonyafaj genetikai vizsgálata: Crataegus nigra WALDST. et KIT., C. pentagyna WALDST. et KIT. és C. chlorosarca MAXIM. Jelen tanulmanyban karpat-medencei “fekete termesű” galagonyak, elsősorban a Crataegus nigra es kozeli rokonainak genetikai kapcsolatait vizsgaltuk intergenikus cpDNS szekvenciak alapjan. Jelentős infraspecifikus variabilitast a kelet-azsiai C. chlorosarca fajnal tapasztaltunk, mig az eurazsiai C. pentagyna eseteben korlatozott szamu nukleotid polimorfizmust azonositottunk. Az altalunk vizsgalt es az adatbazis eredetű referencia psbA-trnH szekvenciak alapjan a Sect. Crataegus es Sect. Sanguineae osztalyozasok tamogatast kapnak. A vizsgalt taxonok, a C. pentagyna es a C. monogyna a Sect. Crataegusba, mig a C. nigra es a C. chlorosarca a Sect. Sanguineae kladokra kerultek besorolasra. Vizsgalataink alapjan a C. nigra a C. × degenii hibrid anyai szulője.
