DNA Markers for Identification of Strawberry (Fragaria x ananassa Duch.) Cultivars Based on Probability Theory

Abstract

DNA fingerprinting of various crops is a powerful tool for preventing the infringement of breeders' rights or incorrect labeling of cultivars; however, techniques with information for probabilistic identification are rare. We examined the independence of 25 cleavage amplified polymorphic sequence (CAPS) markers and the frequency of genotypes detected by each marker to prepare basic information for the probabilistic identification of strawberry (Fragaria x ananassa Duch.) cultivars. We could identify almost 117 investigated cultivars except mutant strains with a probability of at P>99.9% with 16 markers.
