Studies on the varietal resistance of bhendi (Abelmoschus esculentus (L.) Moench) to the leafhopper, Amrasca (= Empoasca) devastans (Dist.) (Homoptera: Jassidae). I. Screening of varieties under field conditions

, : Studies on the varietal resistance of bhendi (Abelmoschus esculentus (L.) Moench) to the leafhopper, Amrasca (= Empoasca) devastans (Dist.) (Homoptera: Jassidae). I. Screening of varieties under field conditions. Madras Agricultural Journal 60(1): 27-31

In two field tests in Tamil Nadu, India, in 1968-69, 25 varieties of Hibiscus (Abelmoschus) esculentus were compared for resistance to Amrasca devastans (Dist.). On the basis of population counts and assessments of damage (hopperburn), three varieties with less than 10 leafhoppers/plant and less than about 20% of the leaf area damaged were classed as resistant.
