Abstract

MAGPANTAY, GERARD B., University of the Philippines at Los Banos, College of Arts and Sciences, March 1989. Succinate dehydrogenase polymorphism in rice (Oryza saliva L.) Major

Adviser: Mr. Ivan Marcelo A. Duka

Succinate dehydrogcnase (SUD) isozymes were detected in 24 traditional Asian rice varieties using polyacrylamide slab get electrophoresis. Zymograms were characterized by three distinct zones of enzyme activity, designated by Sud-1, Sud-2 and Sud-3, each representing a group of adjacent isozymes. Extensive polymorphism were observed among different varieties. Allozymic differences in two of the three isozymes were detected. No significant differences or polymorphisms were observed among tissues and stages of development. The possible biological significance of the study and its applicability for rice breeding are discussed.
