Garlic (Allium sativum L.) has a long history of obligate vegetative propagation. In this study, isozyme and morphological characters were analyzed for 110 diverse clones of garlic and the proposed progenitor species, A. longicuspis. The clones displayed 17 different electrophoretic phenotypes, which were associated with morphological traits. An isozyme-based phenetic tree was contructed to explain the possible relationships of various garlic clones and A. longicuspis. The lack of unique isozyme and morphological characters of A. longicuspis suggests an artificial species separation.
