Crossability of Arachis valida and B genome Arachis species

D. C. Wondracek-Lüdke, Custodio, A. R., Simpson, C. E., and Valls, J. F. M., Crossability of Arachis valida and B genome Arachis species, vol. 14, pp. 17574-17586, 2015.

The peanut (Arachis hypogaea) is an important food crop in much of the tropical and semi-tropical parts of the world. The peanut is an allotetraploid with an AABB genome formula derived from diploids A. duranensis (A genome) and A. ipaënsis (B genome). The success of an introgression program that aims to improve cultivated varieties of the peanut depends on whether the chosen B genome species is homologous with the B genome of the peanut.
