One radiation induced small leaf mutant with foliar disease resistance was isolated in a Spanish bunch variety of VRI 2 groundnut. The mutant VGM-1 was dwarf in nature with small pods and kernels. The mutant showed resistance mechanism for both late leaf spot and rust diseases. The mutant can be utilized as donor parent to develop cultivar with increased level
of resistance.
