| Abstract: | The intergeneric hybrid seedling between apple(M.pumila)and white pear (P.bretschneideri)were obtained in Vitro culture method of hybrid plumules.The exami- nation of chromosomes from their root top and analysis of peroxidase-isoenzyme from leaf and stem showed the hybrid seedling is diploid(2n=34)and shares the main en- zyme zones of their parents. |
