An experiment was carried out during Rabi season 2017 at Oilseed Research Station, Latur, Maharashtra, India. The present study was made to screened 30 sunflower germplasm for their resistance against sunflower leafhopper and whitefly. The cultivar Modern was includedas a susceptible check and KBSH-44as moderately resistant check. It was found that out of 30 germplasm lines, none of the entry was found ‘Highly Resistant’ against leafhoppers while only two germplasm lines viz., GMU-520 and AKSF-6-39 were categorized as ‘Resistant’ germplasms. Sixteen germplasm lines were found as ‘Moderately Resistant’ and eleven as ‘Susceptible’. Among 30 germplasm screened for whiteflies incidence, none of the germplasm was found ‘Highly Resistant’ against whiteflies while three germplasm lines viz., IIOSH-15-10, GMU-520 and AKSF-6-39 were categorized as ‘Resistant’ germplasms. Twenty germplasm lines were found as ‘Moderately Resistant’ and six as ‘Susceptible’. The check Modern was found ‘Highly Susceptible’ to leafhopper and whiteflies.
