Description Recent studies on the genus Arachis using molecular markers have revealed very little demonstrable polymorphism
in the cultivated groundnut, A. hypogaea. This has led to the hasty generalization that the groundnut lacks genetic
variation. However, this is in complete contradiction to the results of other lines of investigations into the origin and
evolution of A. hypogaea. Further, a characterization of the world collection for various traits also shows significant
levels of variation for almost all genetic traits. The literature review in this article suggests that the lack of genetic
variation was inferred because of an inadequacy in the material studied, and the range of techniques used to study
molecular polymorphism. A comprehensive and rigorous examination of the material available in the groundnut
world collection, either by improving current techniques, or by using such advanced techniques as SSRs and AFLP
could well reveal polymorphism at the molecular level.
