| Abstract: | Summary Six zones of LAP activity were detected in apples, some of them tissue specific. Genetic studies in four of them revealed the presence of four genes LAP-1, LAP-2, LAP-3 and LAP-4 with 4, 5, 4 and 4 alleles respectively including two null alleles. There were no big differences in allelic frequency within cultivars, selections, rootstocks and Malus species. Close linkage was found between LAP-2 and resistance to mildew derived from  White Angel . |
