 ABSTRACT

A screening trial with 28 castor genotypes was conducted to assess their relative reaction to leafhoppers (Empoasca flavescens). Among the twenty eight genotypes screened, leafhopper population ranged from 20.48 to 54.28. Highest leafhopper population was recorded in DPC-9 (54.28) followed by DCH-177 (42.93). Least leafhopper population was recorded in GCH-7 (20.48),  VP-1 (20.63). The genotypes DPC-9, PCH-111 and DCH-177 recorded highest hopper burn scores of 2.4, 2.4 and 2.0. Lowest hopper burn scores were found in genotypes GCH-7 (0.00), PCH-254 (0.00), SKI-336 (0.00). The castor genotypes with triple bloom were found to be resistant to leafhopper and genotypes with zero and single bloom were found to be susceptible to leafhopper.

Key words: Castor, Leafhopper, Hopper Burn, Bloom
