Genetic diversity analysis and pedigree evaluation were carried out using Random Amplified Polymorphic DNA (RAPD)
molecular markers on 20 true breeding and high yielding rice genotypes of Kerala. Results show that the genetic base of rice
varieties bred in Kerala is narrowing down, indicating the need to use genetically diverse genotypes in breeding programmes.
We also identified markers that can prove the paternity of certain true breeding rice varieties/cultures of Kerala
