Thermotolerant Saccharomyces strains were crossed with mesophilic Saccharomyces cerevisiae and with cryotolerant Saccharomyces bayanus. The former hybrid is fertile confirming thermotolerant strains as S. cerevisiae. The spores from this hybrid, though, possess a low germinability and give cultures that grow poorly. The hybrid cryotolerant x thermotolerant is sterile and show a new combination of the parental strains' traits improving their technological application. © Rapid Science Ltd. 1998
