Abstract
The study was conducted to assess intra-specific variation and interrelations among morphological, nutritional and biochemical traits in 27 accessions of Jatropha curcas L. Principal component analysis (PCA) explained 58% of the total variation in the measured traits and revealed that there was negative correlation between four morphological traits and all nutritional compounds such as crude protein, neutral detergent fibre, acidic detergent fibre, lignin, hemicellulose and cellulose. Larger plants tended to contain lower concentration of protein and other nutritional compounds. Female flower/inflorescence showed maximum variation, while the difference for the number of male flowers/inflorescence was narrow. This might be explained by the difference in intracellular and extracellular enzymatic activity at different development stages in J. curcas L. A strong correlation between plant height and branch length, number of branches and collar diameter was observed, which can help in the selection of superior genotypes of this species. The highest genetic variation was noticed for polyphenol oxidase analysis. PCA analysis showed that peroxidase activity was associated with cellulase, acid detergent fibre and protein content, whereas polyphenol activity was associated with neutral detergent fibre and lignin content.
