The present investigation was undertaken to study the peroxidase isozymes and mitotisin wheat-rye crosses of four wheat and two rye genotypes to confirm their hybridity. The hybrids showed a combination of both the parental bands along with some new bands at various positions with different intensities. Some parental bands were also missing in all the hybrids. Cluster analysis using the data from peroxidase isozymes indicated that considerable genetic distances existed among the hybrids and their parents. Among the hybrids, maximum genetic distance was seen between Hope x Russian rye and Highbury x Russian rye. Among the parents, Hope was genetically most distant from Rye 8461 indicating that a successful hybrid could be got from them. Mitotic abnormalities of chromosomes in the hybrid root tips were also observed in the form of bridges at anaphase. The somatic chromosome numbers were 21 and 28 in most of the cases, but in one cell 35 chromosomes were seen.
