摘要:
Genetic variation in nine aromatic and four nonaromatic rice varieties (Oryza sativa L.) was investigated at the DNA level using the randomly amplified polymorphic DNA (RAPD) technique. Twenty six random primers were used to amplify DNA segments and 177 PCR products were obtained of which 98 were polymorphic. One primer did not show polymorphism. A dendrogram showing the genetic distances of 13 rice varieties was constructed based on RAPD data.
