Estimation of genetic relationship in germplasm of Jatropha curcas L. based on peroxidase enzyme activity

Among forty accessions studied NRCJ-32 exhibited highest (16.78) activity of peroxidase whereas NRCJ-46 lowest (0.7992) production of this enzyme. The differences observed in the enzymatic activity among the accessions were found adequate to analyze the extent of genetic variability at the intra-specific level. Highest genetic identity was observed between NRCJ32 vs. NRCJ-46 (35.80%) whereas lowest (0.00%) or negligible between NRCJ-35 vs. NRCJ-41. If may help to generate information about growth, development pattern and plant defense mechanism such as stress tolerance, disease resistance of Jatropha curcas L. in terms of enhancement of yield and its components.
