Abstract
Horizontal starch gel electrophoresis was used to study the variation of aspartate aminotransferase (AAT-1), glucose phosphate isomerase (GPI-2), leucine aminopeptidase (LAP-1) and phosphoglucomutase (PGM-1 and PGM-2) isozymes in 76 cultivars and accessions of almond. Cultivars could be separated into 40 classes for identification. Relationships among cultivars, based on historical records and isozyme similarities, show an original pool of seedling selections made before 1900. Most later-introduced cultivars are offspring or descendents of ‘Nonpareil’ and ‘Mission’ (‘Texas Prolific’), the other dominant parent.Keywords
