3. Maize strains with 11 bivalents.

From the translocation mentioned above it has been possible to obtain plants with 11 pairs of chromosomes. They carry no duplication of genetically active chromatin. This increase in chromosome number was a consequence of the breaking of the centromere of chromosome 3 into two portions with both the short and long arms receiving part of the parental centromere.
