Abstract
Lettuce growing in Slovenia has had a several hundred year long tradition. During this time numerous autochthonous varieties have developed among which the most well-known "Ljubljanska Ledenka" grown still today. In the Slovene plant genetic bank there are 170 genetic sources of lettuce acquired by collecting all over Slovenia. For all genetic sources of lettuce basic data on sample, location and characterisation are available but until now they have been evaluated only using morphological markers. The majority of samples were classified into the phenotypic group of crisp-leaved lettuces (about 70%). In the first part of the proposed project we intend to examine the diversity of the Slovene collection of autochthonous lettuce using biochemical and molecular markers (isoenzymes, AFLP) and range the collection in the European and world gene fund of lettuce. The results will be compared with the results obtained at observations of morphological properties. We will focus primarily on the group of crisp-leaved lettuces.
The object of the second part is to investigate the genetic source and reintroduction of the Slovene autochthonous lettuce variety "Ljubljanska Ledenka" which was included in the European Variety Catalogues as "Laibacher Eis" with the characteristic red brim, but which the variety Ljubljanska Ledenka as it is known and marketed today in Slovenia does not have any more. As far as its other properties are concerned it is very similar to the Slovene variety "Leda" which has been developed from "Ljubljanska Ledenka" by selection and it is also the only Slovene variety with DUS test. From the Slovene plant gene bank and other lettuce gene banks in Europe and in the world we would like to find the original autochthonous variety "Ljubljanska ledenka" which will differ from the variety "Leda" and all the other varieties in the Variety List. Trials will be conducted to observe and evaluate morphologic and phonologic parameters according to UPOV descriptors; all the accessions will be analysed using biochemical and molecular markers. The final goal is to classify the variety -"Ljubljanska Ledenka" in the preservation variety list and/or the List of Autochthonous Varieties of Agricultural Plants which is a condition to obtain direct payment per area for the producers of autochthonous and traditional varieties of agricultural plants and to obtain similar support from the funds of European Union. If we find a type which will differ from types described until now in the European Variety Catalogue and from the variety "Leda", we will start the procedure required for the inscription in this catalogue. The study of genetic origin of autochthonous variety "Ljubljanska Ledenka" will contribute to the extension of knowledge in the field of research of gene flow and genetic erosion of lettuce in the world.
