Abstract

This thesis contains the published results of the ”Development of generative propagatable high yielding lines of lemon balm (Melissa officinalis L.) via conventional generating of homozygote lines as a prereqisite for synthetic and hybrid variaties” (original title in German: „Entwicklung generativ vermehrbarer Hochleistungslinien von Zitronenmelisse (Melissa officinalis L.) durch konventionelle Erzeugung homozygoter Linien als Voraussetzung für Synthetiks oder Hybridsorten“) which was part of the project “Improving the international position of the German production of medical herbs and spices, by taking the example of the optimisation of breeding and cultivation of valerian, camomile and lemon balm.“ and was funded by the Fachagentur für Nachwachsende Rohstoffe . The papers “Chromosome number and ploidy level of balm (Melissa officinalis)”, “Evaluation of 28 balm and lemon balm (Melissa officinalis) accessions for content and composition of essential oil and content of rosmarinic acid” and “Content and composition of essential oil and content of rosmarinic acid in lemon balm and balm genotypes (Melissa officinalis)” contain important results for modern breeding attempts in lemon balm. The publications show the characteristics of the accessions and genotypes such as ploidy status, content and composition of essential oil and content of rosmarinic acid. Of particular importance are the first descriptions of triploid Melissa genotypes, as well as three Melissa chemotypes, which have never been outlined before.
