Abstract

Triploid and aneuploid strains of the xylose-fermenting yeast were constructed. This species is a strongly homothallic organism in which the haploid phase normally predominates. The technique for producing polyploids involved prototrophic selection and interruption of the normal sequence of events leading from nuclear fusion to meiosis. Confirmation of triploidy was obtained by tetrad analysis. The haploid chromosome number of was estimated to be between 5 and 7.
