Abstract

Embryo and endosperm peroxidases from dry mature seeds of three subspecies of tetraploid wheat (Triticum turgidum L.) were subjected to genetic analysis. The inheritance of eight isozymes (embryo isozymes a2, d1, d2, e and f; and endosperm isozymes b, d and 4) were studied in F2's obtained from different wheat accessions. Simple monogenic inheritance producing three banded: one null segregation and two epistatic segregations (9∶7 and 15∶1) were found. In the case of isozymes b, d and 4, monogenic or epistatic segregation depended on the F2 analyzed. Segregation data indicated that at least 9 different loci would determine the peroxidase isozymes of tetraploid wheat seed, all the loci studied containing 'null' alleles. Furthermore, several loci determining embryo peroxidases were noticed to be mutually linked. All these data are discussed in context of the inheritance of seed peroxidases in hexaploid wheat and rye.
