The study was conducted for preliminary screening trial of 30 genotypes of okra for relative
susceptibility/resistance against jassid, Amrasca biguttula biguttula (Ishida) during 2006. From these screening
trials 3 genotypes showing comparatively susceptible (Pusa sawani, Dera local and Okra-3), 3 with intermediate
(Karam-5, Sabz pari and Clean spineless) while 3 with resistant (Makhmali, Punjab selection and Green wonder)
responses against jassid were selected for final screening trial during 2007. Differences were found to be
significant among genotypes of okra during both the study years. The trend in selected genotypes towards
susceptibility/resistance against jassid was similar to that observed during preliminary screening trial. Pusa
sawani showed maximum Host Plant Susceptibility Indices (HPSI) i.e. 18 % and was susceptible, while Green
wonder was comparatively resistant with minimum HPSI i.e., 5 %.
