Abstract

Among the 8 genotypes screened, RG 1068, ICI-RG2661-7-5-1-7, ICI-RG2661-16-2-2 was found to be resistant to leafhopper with lowest leaf hopper population of 0.0 numbers/ 3 leaves/plant with hopper burn grade of 0. Among the accessions, thrips population was lowest in RG 22 (3.2 No/spike), RG 3198 (7.30 No. / spike). The remaining entries and the check entries recorded moderate thrips population which ranged from 12.30 to 24.60 numbers/spike
