Abstract
This paper reports the initial experiments for genetic analysis of the haploid methylotrophic yeastCandida boidinii PLD1. The collection of multiply marked auxotrophic mutants was obtained after treatment with UV-light or X-rays. Protoplasts from several mutants were fused by the PEG-CA2+ technique and five prototrophic hybrids were isolated. The genetic structure of the hybrids was studied by means of spontaneous and induced mitotic segregation. Our data suggest that hybrids are diploids, heterozygous by parental auxotrophic markers. We obtained genetic linkage between mutationslys2-8-met-3 from one hand andade-17-arg-24 from the other. The genetic maps constructed showed similar characteristics concerning both the order of the markers and their map distances.
