Thirteen (Three gynoecious and ten monoecious) germplasm lines of cucumber (Cucumber sativus L.) were characterized by sodium dodecyl sulphate polyacrylamide vertical slab gel electrophoresis (SDS-PAGE). The seed protein could be resolved into total 11 bands distributed in 4 zones . A, B, C and D. Zone A was divided into 5 subzones and 5 bands, zone B has 1 band C has 5 and zone D included 5 bands. Similarity index value ranged from 62% to 100% among all the genotypes. Pgyn-1 showed least similarity 68% with other genotypes. It was observed that all the gynoecious genotypes were dissimilar to monoecious genotypes. | Electrophoretic characterization of gynoecious and monoecious cucumber Cucumis sativus L. genotypes based on seed protein profiles
