Uittreksel

Western Europe is the world's greatest leek producing and consuming region. Belgium is situated in the centre of Western Europe and can be considered as a genepool of landraces of leek. Although the commercial varieties nowadays take over the successes of Belgian landraces, this paper deals with the breeding potential of the Belgian landraces. Typing the Belgian landraces was done in an observation trial together with 50 cultivars. Clustering analysis revealed that 4 of the Belgian landraces were autumn types, 2 landraces were of the early winter type and another 12 landraces were ranged with 6 commercial varieties to form the most winterhardy group of leek. For the important characteristics leaf colour and senescence resistance, the Belgian landraces were better than most of the commercial varieties. Although, for economically more important characteristics shaft length and some disease resistance they scored low. Finally, in this trial, the Belgian landraces were high yielding, especially in the late season. But also in the early season (harvest in September and November) some Belgian landraces were in the top 10 for yield. At harvest in February 9 of the 10 best yielding winterleeks were Belgian iandraces. This proves that the Belgian landraces were well adapted to the soil and climate of this region.
