Abstract

The extent of genetic diversity among 17 seed sources of Jatropha curcas was studied using 13 ISSR primers along with its combinations. The number of bands produced by 13 individual primers ranged from 1 to 10. The percentage polymorphism or
polymorphic percentage ranges from 100 to 33.3 and the PIC value varied from 0.89 to 0.65. Among 13 ISSR primers, two primers viz., 895 and 899 produced 100% polymorphism.These genotypes were also tested with 78 combination primers for its amplification. Out of seventy eight combinations, eight combinations were found to exhibit 100% polymorphism and its PIC value ranged from 0.86 to 0.38. The genetic similarity index was used to construct a dendrogram which illustrated that the 17 genotypes fall into five clusters at 0.72 Jaccard’s similarity coefficient and the same data was used to construct the radial tree using Darwin software. Both these software identified the two genotypes CJC 1 and CJC 19 as diverse. These diverse accessions can be utilized in breeding programme to obtain more variability.
