The ferfrlrty observed rn trrplod hybrrds of A hyp0g.m and erghf drplotd spocres. and the
recovery of progenres wrfh drplord to hexapkrd chromosome numbers hrve led to the rdentrlrcafron

from the trrplord hybrrds show rntra- and rntergenomrc parrmg rn the form 01 btvalents rndmult~vrlents.
Hexeplords and the progenres of the trrplords were backcrossed wtth A hypogaee and
produced A hypogaea-lrke dertvatrves
