GENETIC-ANALYSIS OF ISOENZYME VARIATION IN MEDITERRANEAN CYPRESS (CUPRESSUS-SEMPERVIRENS L)

Our inability to separate the haploid megagametophytic tissue from the diploid, maternal perisperm in the seeds of Mediterranean cypress was the reason for using single tree progenies from open pollination for the genetic analysis of isoenzyme phenotypes. Isoenzyme patterns from seed perisperms (maternal tissue) and seed embryos (progeny tissue) we re compared and tested qualitatively and quantitatively for the mode o f inheritance. In total, 8 variable proposed gene loci coding for 7 en zyme systems could be identified. The data of genetic analysis support ed the intuitive genetic interpretation of the isoenzyme patterns.
