Abstract: Sorghum [Sorghum bicolor (L.) Moench] is an important cereal crop in India popularly known as ‘Jawar’ or ‘Great millet’. In Maharashtra about 18 important insect pests have been recorded on sorghum crop. In sorghum major incidence of shootfly, stem borer and sorghum aphid are observed. In screening programme in all thirty two sorghum genotypes including three checks were replicated twice under Randomized Block Design for resistance to mention insect pest. The ovipositional preference by shoot fly depends on particular trait. Non preference for shoot fly egg laying skip the crop from the damage by shoot fly. In addition resistant checks IS-18551 and IS-2205, the test entries Surgaon L., IS-31420,PVR-660, PVP-657, IS-24308, IS-17666, IS-26998, Pop sorg.19, IS-13721, IS-40838, IS-30970 and IS-5150 had less preference for egg laying by shoot fly along with resistant characters, test lines Surgaon L., IS-31420, PVR-660, PVP-657, IS-24308, IS-17666 and IS-26998 can tolerate shoot fly damage. Glossy seedlings are having low seedling score and vigorous seedling having low seedling vigour score and seedling vigour score was significantly and positively associated with shoot fly egg and shoot fly incidence. Hence, the lines with glossy and vigorous behavior can be incorporated in breeding programme for developing shoot fly resistant material and can be advised to farmers for growing in shoot fly hot spots.
