Abstract
1. Sporulation in Saccharomyces cerevisiae is influenced by the genetic constitution of the culture as well as by the composition of the nutrient medium. A specific nutrient medium which gives maximum sporulation has been developed and described. 2. On this medium, heterozygous, legitimately diploid cultures produce an abundance of viable 4-spored asci. Single ascospore cultures (which may be either illegitimately diploid or haploid) sporulate much more irregularly; some do not sporulate at all. The asci from single ascospore cultures generally contain only one or two spores, and their viability is much diminished. 3. A survey of forty commercial baking yeasts was made. Some were legitimately diploid, while others were of single ascospore origin.
