Abstract: A study was initiated to categorize the seeds of various wild and cultivar legume varieties on the basis of their relative resistance to the bruchid, C. maculatus, and to correlate the important primary and secondary metabolites (non-protein antimetabolites) in these seeds to the developmental parameters of the bruchid. In general, the wild seed varieties showed greater amount of resistance to the bruchid attack when compared to that of the cultivar varieties. All the cultivar varieties studied showed higher amounts of primary metabolites, namely, proteins, carbohydrates, lipids and free amino acids thus showing a positive correlation between the primary metabolites content and the infestation rate. The wild varieties, however, showed significantly lower amounts of these primary metabolites and consequently a lower level of infestation. The non-protein anti-metabolites such as total phenols, ortho- dihydroxy phenols and tannins were significantly lower in the cultivars. The wild varieties, in contrast, revealed higher amounts of these secondary metabolites showing a negative correlation between these secondary metabolites content and the infestation rate. The study revealed that these non-protein anti-metabolites are important in conferring resistance to the seeds.
