Abstract

A comparative immunological survey of the proteins in 36 species accessions of the genus Arachis as grouped by Gregory et al. (1973) conducted by using immune sera from cultivated peanuts showed both quantitative and qualitative differences in protein contents. Sections I (Axonomorphae) and II (Erectoides) contained higher concentartions of the major peanut globulin, a-arachin than sections III (Caulorhizae), IV (Rhizomatosae), V (Extranervosae), VI (Pseudoaxonomorphae) and VII (Triseminalae). The precipitin patterns of total proteins in sections I, II, and IV appeared very similar to the precipitin pattern of the cultivar Virginia 61R. In general, the total precipitin patterns of sections III, V, VI, and VII showed relatively higher quantities of the albumins and the conarachins than did precipitin patterns of the other sections and their total patterns were less similar to the total pattern of Virginia 61R. Both intraspecific and interspecific polymorphism of proteins existed throughout the seven sections as evidenced by immunochemistry.
