Using the new yeast Schizosaccharomyces kambucha nom. nud. and genetic lines, widely explored in different laboratories, we continue the investigation of the phenomenon of ascospore death in interstrain hybrids of Sch. pombe. All interstrain hybrids were sterile when analyzed by a micromanipulator. However random spore analysis revealed recombination of control markers, suggesting assignment of the strains studied to the same biological species Sch. pombe. Possible causes of hybrid ascospores death are discussed. The population antagonism of the yeast Sch. pombe should be taken into account in taxonomic studies.
