ISOENZYME VARIATION IN CUCUMIS SPP.

Abstract

Isoenzyme variation in 13 species of Cucumis, including C. melD and C. sativ us, was studied for three enzyme systems, viz. peroxidase, GOT and GDH. The species showed very little similarity for PRX and GDH zymograms. However, there was high degree of similarity among the species for GOTzymogram. All the species possess a genus-specific isozyme at GOT4. There was very little similarity among the species for the three isozymes put together. No Cucumis species of African origin seem to have contributed to the evolution of C. melo.
