title: Genetic characterisation of New Zealand and Australian wine yeasts. Occurrence of killer systems and homothallism.
abstract: Twenty five culture wine yeast strains from New Zealand and Australia were examined for killer capability or sensitivity. Eight yeast strains were K2 + killers, six of the K2 + R1 - R3 + phenotype and two of the K2 + R1 - R3 - 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.
