Popis:	Selected stable standard Solanum genotypes and two populations of asymmetric somatic hybrids between Solanum brevidens (2n=2x=24) and dihaploid S. tuberosum (2n=2x=24) were analyzed to test the resolution of flow cytometric determination of nuclear DNA content (2C value) in terms of a loss or gain of chromosomes, and to analyze the correlation between the 2C value and the chromosome number. Correlation was high within the standard genotypes (r=0.99, P
