Measurement of genetic dissimilarity in fieldpea (Pisum sativum L.) genotypes using RAPD markers
2007
Yadav, Vinod Kumar | Kumar, Sandeep | Panwar, Ravindra K
The present investigation was carried out on fifteen germplasm lines of Pisum sativum L. were used for characterization using Randomly Amplified Polymorphic DNA (RAPD) markers. While 12 random primers were taken, out of them 11 primers gave amplification. These primers gave a total of 133 bands out of which 106 were polymorphic. Genetic similarities of the RAPD profiles were estimated by using Jaccard's coefficient with NTSYSpc 2.0 software. The similarity index values ranged from 0.263 to 0.793 indicating the presence of enormous genetic diversity at molecular level. A dendrogram generated by cluster analysis divided fifteen fieldpea genotypes into two Groups A and B. Major Group A have five genotypes and major Group B have nine genotypes.
