Bael is the one of the most important indigenous fruit of India. The experiment on role of peroxidase isoenzyme in self- and cross-pollinated cultivars of Bael was laid out at G.B.P.U. A & T, Pantnagar during May 2003 to June 2004. The selfed and crossed pistils at various time intervals were analyzed for peroxidase isoenzyme activities through Polyacrylamide Gel Electrophoresis. Pollens of all the cultivars exhibited two different bands with Rm 0.21 and 0.90 at different intervals. However, pistils showed only a single peroxidase band at Rm. 0.23. Selfed pistils of cv. Pant Aparna while Pant Sujata separated two bands (B band Rm 0.18, C band Rm 0.25) and (B band Rm 0.17, C band Rm 0.26), respectively, at various timing of styler exicision. In Pant Shivani (A band Rm 0.06, B band Rm 0.17 and C band Rm 0.30) and Pant Urvashi (A band Rm 0.07, B band Rm 0.18 and C band Rm 0.31) three different bands were isolated with different staining intensities and motilities at 144 and 216 hours after pollination. Similarly, the crosses also depicted two or three bands at different time intervals. Therefore, no definite interaction could be established in peroxidase activities in both self- and the cross-pollination in Bael cultivars.
