Abstract excerpt
A strain of Saccharomyces cerevisiae having desirable winemaking properties and high spore viability was bred from a semi-homothallic parent strain with similar winemaking properties but that produced sixfold fewer viable spores. Because the parent was homozygous for HO and for the MATa allele at both silent HMR and HML loci, it produced two MATa and two nonmating progeny per ascus. To obtain a segregant able to...
