✦ Synopsis
The morphological variation and the isozymic polymorphism in 19 asparagus accessions currently used in cultivation and breeding are described . Moreover 2 wild populations from Turkey were added in the isozymic study . Characters of ramification height permit to separate accessions usually cultivated for white asparagus and accessions usually cultivated for green asparagus . Starch and polyacrylamide gel electrophoresis was realized to assay 7 enzyme systems . 29 polymorphic bands were taken into account in the study . Four accessions show specific bands for glutamate oxaloacetate transaminase, shikimate dehydrogenase and alcohol dehydrogenase . In particular, the two populations from Turkey and one population traditionally cultivated in local area of Spain are well differentiated from the remaining accessions . Accessions from the United States representing different selections are relatively well separated from each other .
