Abstract: Seed storage protein markers being less sensitive to environmental fluctuation than phenological traits, has been successfully employed in assessing divergence in many crop plants. The present study was aimed to find out correlation of seed storage protein markers in twenty eight Indian sesame cultivars with their agro-ecological zone of adoption and their seed coat colour. Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) revealed altogether twenty two protein bands of which thirteen were polymorphic with varied molecular weights. Specific bands, relating to specific agro-ecologies were found. Moreover, bands of 93.40 KDa and 68.05 KDa were found associated with production of darker shades of seed coat colour. Clustering pattern based on protein similarity value offered no definite grouping, either to specific agro-ecological zones of adoption or to specific seed coat colour. It is concluded that individual protein banding pattern can be linked to agro-ecological adoption zone and seed coat colour which is helpful in divergence and phylogenetic study in sesame.
