Abstract

Twenty five culture wine yeast strains from New Zealand and Australia were examined for killer capability or sensitivity. Eight yeast strains were K +2 killers, six of the K +2 R -1 R +3 phenotype and two of the K +2 R -1 R -3 phenotype. The seventeen sensitive strains were separated into four phenotype classes. The homothallic life cycle was detected in twenty-one strains and one further strain is probably triploid.
