Discrimination of Blue and White Flowered Clitoria ternatea Linn. (Fabaceae) Through RAPD assay

RAPD finger printing was used to measure the relatedness between the populations. RAPD primers were screened on a pool of genomic DNA of 16 samples of Clitoria ternatea bearing blue and white flowers. For each (both blue and white) variety, the DNA extracted from 4 individual from within the population (intra). The polymorphic amplified fragments were observed for 5 primers namely OPB - 11, 12, 17, 18 and 20 with high reproducibility. The percentage of polymorphism recorded was 48.1%. The genetic similarity matrix for inter and intra variation was calculated by primer wise comparison of 4 individuals of each blue and white populations.
