Radiation-induced mutants of groundnut cv. Spanish Improved showing di
stinct morphological differences and the parent were screened for RAPD
variability. The analysis revealed characteristic band differences am
ong the 12 mutants and the parent. The polymorphic RAPD bands were dom
inant in the F-1 and segregated in a Mendelian fashion in the F-2. The
RAPD technique brought out greater genome variability than RFLP.
