AbstractThe inheritance ot nine isozyme systems in selfed progenies of chives was studied elcctrophoretically. The isozyme systems studied were malate‐dehydrogenase (MDH), phosphoglucoisomerase (PGI), triosephosphate‐isomerase (TP1), diaphorase (D1A), menadione‐reductase (MDR), esterase (EST), glutamate‐oxalacetate‐transaminase (GOT), hexokinase (HK) and superoxide‐dismutase (SOD). Segregation results of Goodness‐of‐Fit tests against the expected 1:2:1 and 3 : 1 ratios for codominant and dominant inheritance, respectively, led to the identification of 16 isozyme loci whose banding patterns are given in this paper. The first results on linkage relationships between isozyme loci and between theMdr‐3‐locusand a male sterility gene are given. These results and further studies will be used to mark important c
