Backcrossing to increase meiotic stability in triticale

R. M. Giacomin, Assis, R., Brammer, S. P., A. Junior, N., and Da-Silva, P. R., Backcrossing to increase meiotic stability in triticale, vol. 14, pp. 11271-11280, 2015.

Triticale (X Triticosecale Wittmack) is an intergeneric hybrid derived from a cross between wheat and rye. As a newly created allopolyploid, the plant shows instabilities during the meiotic process, which may result in the loss of fertility. This genomic instability has hindered the success of triticale-breeding programs. Therefore, strategies should be developed to obtain stable triticale lines for use in breeding. In some species, backcrossing has been effective in increasing the meiotic stability of lineages.
