Abstract

The individual characteristic features of chromosomes
in Petkus rye (diploid) and 82 hexaploid triticale accessions
were assessed to identify the replaced rye chromosome
pair(s) in triticale and its effect on kernel characters. GiemsaC-banding technique was used for the study. Results
revealed that 24 hexaploid triticales showed full
complement of rye chromosome, 34 had replacement of
one pair and 24 had replacement of two pairs of rye
chromosomes. Triticale strains with 2R/2D and 4R/4D
substitutions had higher and medium seed set, respectively.
Seed set was considerably high when both with 2R/2D
and 4R/4D substitution occured together.
