Eleven enzyme systems encoding for 18 isozyme loci were analysed by horizontal starch gel and vertical polyacrylamide gel electrophoresis in female gametophytes of English yew (Taxus baccata L.). The descriptions from THOMA (1992) and LEWANDOWSKI et al. (1992) were completed with some additional isozyme markers. No deviations from the expected 1:1 segregation were found at the 14 polymorphic loci AAT-B, AAT-C, ADH-A, ADH-B, IDH-A, IDH-B, LAP-B, MDH-A, MR-A, NDH-B, PGDH-A, PGI-B, PGM-A and SKDH-A. The material allowed to examine 78 two-locus combinations for linkage relationships. The most remarkable linkage was detected between the loci PGM-A/PGI-B with a recombination frequency of 0.21 at all of the 6 trees tested. Further, the analysis resulted in the linkage groups IDH-B/SKDH-A (recombination frequency 0.26) and ADH-A/LAP-B (recombination frequency 0.33) at 2 resp. 3 individuals. Additionally, 10 two-locus combinations with recombination frequencies in the range of 0.21 to 0.35 were found in only one of the investigated trees. Some polyembryonic seeds were revealed by their 2-allelic patterns in the gametophyte tissue of heterozygous mother trees.
