Figure 2. PCR amplification products using gwm 60 microsatellite. Genomic DNAs were extracted from isolines of: Prointa Puntal-Lr47 (lanes 1-2), Prointa Oasis-Lr47 (4 to 7), Pavon-Lr47 (8 to 10), Kern-Lr47 (12-13) Prointa Puntal without Lr47 (3), Pavon (11) and Kern (15). M is a DNA size standard (Biodynamics). A white arrowhead indicates the position of the PCR fragment associated with Lr47.
