Summary
GDH isozyme patterns from field collected plants of Hymenopappus scabiosaeus are examined. Some of the apparent heterozygous patterns consist of one broad band while others contain five discernible sharp bands. Resolution of these bands apparently depends upon the distance separating the parental phenotypes on the gel. These observations support a model proposed by Pryor (1974) which states that GDH in maize may be composed of multiple sub-units but that the resulting isozyme bands do not resolve on a starch gel because of their close proximity.
