Technical Abstract: Garlic (Allium sativum L.) is valued for its culinary and neutraceutical qualities. Farmers grow hundreds of differently named garlic accessions in the United States. A genetic analysis was performed to determine the extent of duplication and diversity across these garlic accessions. Phenotypically distinct types of garlic (porcelain, rocambole, silverskin, artichoke, purple stripe, marble purple stripe, and Asiatic) were identified using genetic markers. These data are useful for vegetable growers that seek to ensure they are growing diverse garlic types on their farms.
