abstract
The leafhopper, Empoasca kerri Pruthi is one of the major sucking insect pest of groundnut (Arachis hypogaea L.) responsible for reduction of plant growth and yield. Ten diverse genotypes were evaluated to estimate the resistance in semi-arid region of Rajasthan, India during Kharif 2018. On the basis of mean population of the season on different genotypes and varieties of groundnut crop the ascending order of leafhopper infestation was found in order as:RG-510 < TAG-24 < RG-632 < RG-559-3 < RG-622 < RG-625 < TG-37A < RG-425 < RG-578 < RG-382. Based on the statistical categorization RG-510, TAG-24 and RG-632 were shown highly resistant reaction, RG-578 and RG-382 showed least resistance while, rest of the varieties and genotypes were moderately resistant against leafhopper. The resistant genotypes may be recommended for testing their performance under different agro-climatic conditions and/or may be further utilize as donor parents in breeding programs of groundnut.
