The isozymes for 10 enzyme systems were electrophoretically investigated in Stellaria longipes and Stellaria longifolia. Twenty-six isozymes were detected in S. longipes, 21 of which were found in S. longifolia. Twenty-six gene loci were inferred to control these isozymes; 19 were confirmed by selfing and crossing experiments. The intergenic relationships were examined among 34 pairs of genes. The genetic basis of isozymes was documented. Only four pairs of genes are inherited as linkage, and others were confirmed to be inherited independently.
