Triticale Breeding

Producing primary triticales in the greenhouse 



Nach oben

The following scheme illustrates how primary triticales are made by single crosses:



Nach oben

Mother Father Primary Triticale
Soft wheat, hexaploid, Genome: AABBDD Rye, diploid, Genome: RR Primary triticale, octoploid, Genome: AABBDDRR
Hard wheat, tetraploid, Genome: AABB Rye, diploid, Genome: RR Primary triticale, hexaploid, Genome: AABBRR

Secondary triticales are obtained by crossing two differently composed primary triticales as shown below:

Mother Father Secondary Triticale
Primary triticale, octoploid, Genome: AABBDDRR Primary triticale, hexaploid, Genome: AABBRR Secondary Triticale, hexaploid, Genome: AABBRR

The diversity of triticale lines can be augmented by producing substitution triticales as follows:

Mother Father Substitution Triticale
Soft wheat, hexaploid, Genome: AABBDD Secondary triticale, hexaploid, Genome: AABBRR Substitution triticale, hexaploid, Genome: AABBRR or AABBRD

For a better understanding, the above schemes have been simplified. Mostly, a qualified variety is made up more complicated. After crossing work has been finished, selection work is carried out in breeding plots:

Selection within small plots

Laborious detailed work is necessary to select the promising lines which have to be multiplied and selected anew through several generations for yield and other characters on different locations.

It takes 15 years and more from the first cross to the official release of a variety which is precondition for marketing the seeds.
