Title Genetic lntrogression from Compatible Wild Species into Cultivated Groundnut
 
Creator Singh, A K
 
Subject Groundnut
 
Description The drplord wrld speoes (2n.20) compahble wrth the cultrvatcrd letraplord groundnut A hypogee8
(2n=IO). are sources of resrstance to many drseasss of groundnut
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
of a raprd method for the productron of retraplord rnterspecrfrc derrvatrves T h e henaplords rarsed
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
Autotetraplo~ds were crossed wrth A hypcqsee end some lerfrle F I progenres obtsrned
Forty-SIX 01 the 56 possrble ~nferspecrfrc crosses among erght drplord wrld specres producad
seeds Amphrplotds were esleblrshed rn 31 combrnatrons. 23 have been crossed wrth A hypogaea
