摘要
Anonymous DNA fragments from the genome of cultivated avocado (Persea americana Mill.) were cloned into a plasmid vector and used to screen a total of 36 cultivars. There is a high level of polymorphism among cultivars allowing all cultivars to be assigned a unique genotype based on 14 genetic loci. A cluster analysis of genetic similarities among cultivars revealed three major clusters that correspond to the three major racial groupings of cultivated avocado. Additional clusters appear to reflect cultivars derived through interracial hybridization.
