✦ Synopsis

Seven varieties and 57 spontaneous or induced in vitro mutant lines (20 macromutant and 37 micromutant events) of potato were tested by starch gel electrophoresis for ADH, GOT, PGI, PGM, ACO, IDH, MDH and 6PGDH isozymes in tuber extracts. The data showed that in contrast to variety comparisons, the isozyme patterns rarely differentiate mutant lines which have altered morphological traits. But trying to identify isozyme differences in mutants can still be useful for a chimeric structure for GOT-2 alleles in a mutant from Atlantic and a new tuber specific locus for 6PGDH in mutants from Russet Burbank were found.
