IDENTIFICATION OF GROUNDNUT GENOTYPES LESS SUSCEPTIBLE TO DAMAGE BY LEAFHOPPER, EMPOASCA-DOLICHI (PAOLI) IN ZAMBIA

Field experiments at the Msekera Regional Research Station during 1988 -1990 and at Masumba (Luangwa Valley) Sub-station during 1989-1990 sho wed that six groundnut genotypes - ICG.485,ICG.2271, ICC;.2306,ICG,504 1,ICG,5045 and HyQ (cg)S-10 were distinctly less susceptible to the le afhopper, Empoasca dolichi (Paoli),ICG.2271 also appeared to combine l ow susceptibility to early leaf spot, Cercospora arachidicola Hori and good yield potential, This genotype as well as ICG,5041 and ICG.5045 also are known to be resistant to thrips and/or termites, The scope fo r their utilization in exploitation of leafhopper resistance in ground nut improvement programme in Zambia is indicated.
