Geneticists working in an agriculture lab wanted to develop a crop that combines the disease resistance of rye grain with the high crop yielding capacity of wheat grain. Rye grain has a diploid chromosome number (2n) of 10 and wheat grain has a diploid chromosome number of 16. The resulting grain is called triticale and is an alloploidy plant. How many chromosomes are found in the pollen grain of triticale

As it is an alloploid cell, it must be taken into account that it is the definition of: "composed of 2 or more genomes of different origin (of different species). They arise from crosses between individuals of different species or generation.

Using the technique of: obtaining a hybrid and subsequent chromosomal duplication by action of colchicine, some alloloids with some stability and more or less Improving success. Triticales are a good example, hybrids of rye and wheat, (Triticum eastivum gives rise to octoploid triticales and Triticum durum hexaploid triticales genera). In both cases there are problems of stability that relates to quantity of heterochromatin from the chromosomes of rye and with the regulation of diploidization which is made by the wheat Ph1 gene fundamentally and that by shortening the time of mating causes some to be lost rye chromosomes. Large amounts of triticales have been obtained, currently being used as forage plants but they are also used to take advantage of the seeds and they are already commercialized with some success "tritiflakes".
