Assessment of antixenosis and antibiosis levels in rice genotypes against Sogatella furcifera (Hemiptera: Delphacidae)

White-backed planthopper, Sogatella furcifera Horváth (Hemiptera: Delphacidae) is a migratory and serious pest of rice crop worldwide including Pakistan. The current experiment was carried out to assess the antixenosis antibiosis level fifteen genotypes against S. under greenhouse conditions. In studies, proportion nymphs adults settled recorded in relation control. Less preferred varieties by were RPP49 (3.80), N22 (5.60), IR 64 (6.20), 72 (6.60), Basmati Pak (6129) (5.40), Super (5.00) as compared TN1 (12.00). Lower number eggs laid on RPP49, N22, 64, PKBB 8. Based feeding marks ranked from highest lowest Pak. tests, IR64, 72, performed well TN1. Minimum rate (47.8 mm2) followed IR74, Pak, Basmati, 8, PK 10684 10436 TN1(470.8 mm2). results revealed that emerged new resistant source furcifera. have shown moderate resistance while are with which can be used breeding programs
