Description Cultivated groundnut (Arachis hypogaea) is made up of
two genomes, A and B. It is presumed that polyploidization
event between diploid A and B genome species gave rise
to cultivated tetraploid groundnut some 3500 years ago
(Singh and Simpson 1994). There is no ambiguity regarding
A. duranensis as the A genome donor of A. hypogaea
(Gregory and Gregory 1979, Singh 1988, Kochert et al.
1991, Paik-Ro et al. 1992, Stalker 1992). Different species
from the B genome pool have been proposed as the B
genome donor. According to Singh (1998), A. batizocoi
is the B genome donor. Based on RFLP (restriction
fragment length polymorphism) studies, Kochert et al.
(1991) have suggested A. ipaensis as the B genome
donor. According to Paik-Ro et al. (1992), A. batizocoi is
not closely related to A. hypogaea and hence cannot be
the B genome donor. Karyotype studies of Fernandez and
Krapovickas (1994) support A. duranensis and A. ipaensis
as the A and B genome donors of A. hypogaea.
