IDENTIFICATION OF CITRUS CHIMERAS BY RAPD MARKERS

Random amplified polymorphic DNA (RAPD) markers were used to detect ch imerism of citrus cultivars. Polymerase chain reaction conditions suit able for discriminating citrus chimeras were determined. Primers that produced consistent and repeatable bands that differed between the par ental cultivars were chosen to create discriminating band patterns, Ou r results show that selected 12-mer primers can be useful for identify ing the four citrus chimeras tested using RAPD technology.
