Collection and Electrophoretic Characterization of Genetic Diversity in Muskmelon (Cucumis melo L.)

Abstract

Seed storage protein protiles of muskmelon genotypes were analysed on single seed basis by Sodium OodecylPolyacrylamide gel electrophoresis (SOS-PAGE) under reducing condition. The seed protein of 32 germplasm lines could be resolved into 18 bands distributed in 3 zones A, Band C zone. In general there was very high similarity between genotypes of muskmelon, apart from some minor differences in the B region while the seed proteins of different cucurbit species show polymorphism. This shows that SOS-PAGE is not very effective for distinguishing muskmelon genotypes and it will be desirable to use ONA-based markers.
