Zusammenfassung:	A light green mutant was found in a population of adapted cultivated diploid potatoes. Genetic analysis indicates that this trait is controlled by a single nuclear gene. The gene symbol lg is proposed. The segregation ratios fit a pattern which strongly suggest that there is a close linkage between the Lg allele and a locus which confers lethality in its homozygous recessive state. Some crossing over between the lg locus and the lethal was found to occur but LgLg genotypes were not observed in progenies from sib-matings. The lg locus mapped to the potato linkage group VI between the restriction fragment length polymorphism (RFLP) loci CP18 and GP24.[PUBLICATION ABSTRACT]
