Abstract

The peroxidase banding patterns in leaves of three varieties of abaca (Puss textil.is Nee), one pacol (Musa balbisiana Colla) variety, four putative hybrid varieties (one of minay and three of canton), and three artificial F1 hybrids were studied using polyacrylamide disc gel electrophoresis. A total of 12 bands were detected in the different species studied, two being common to all the hybrids and the parents (Rf= 0.337 and 0.406). r:), r, chewed a 0.768 band unique to it and a low mobility 0.118 band. Pacol did not show any low mobility band but had a 0.452 band which was absent in abaca. Two F1 hybrids 'showed the same pattern as pacol. The third F1 hybrid and all putative hybrids showed the 0.452 band of pacol and two to three low mobility bands with .two hybrids showing the same low mobility band Rf value as abaca (0.118). These results indicate similarity of the said hybrids to both parents and hence verifies hybridity. Further, that putative hybrid patterns are closer to abaca compared to F1s support previous hypotheses on their origin as backcross progenies between natural F1 and the abaca parents.
