abstract
The present study was conducted for screening of rice germplasm against major insect pests under Eastern Uttar Pradesh conditions for two consecutive years, 2014 and 2015 at farmer field of district Deoria. There were 27 rice germplasm screened against major insect pests of rice comprised of 3 local checks and 24 new entries under augmented block design (ABD). The screening of rice germplasm resistance against major insect pests of rice was evaluated as per methodology of IRRI-Standard Evaluation System for Rice (SES) (IRRI, 2013) modified as accessibility. The germplasm resistance was varied in highly resistance, moderately resistance, moderately susceptible, and highly susceptible scale of germplasm screening. The infestations of major insect pests of rice were observed for most serious insect pests, i.e., 1. Yellow stemborer (Scirpophaga incertulus Walker), 2. Common rice leaffolder (Cnaphalocrosis medinalis Guenee), 3. Brown planthopper (Nilaparvata lugens Stal), 4. Rice hispa (Dicladispa armigera Oliver), and 5. Rice earhead bug (Leptocorisa acuta Thunberg) specially. The highly resistance, moderately resistance, and moderately susceptible rice germplasm were observed for all major insect pests of rice except Rice earhead bug (Leptocorisa acuta Thunberg) not confined moderately resistance germplasm. The highly susceptible germplasm were not observed for any major insect pests of rice. Whereas, the mean infestation of major insect pests of rice was observed only highly resistance and moderately resistance germplasm. There were 19 rice germplasm (TCA 80-4, NDR 8002, PSBRC 70, RR 347-166, NDR 3112-1, NDR 2064, SARJU-52, GOVIND, NDGR 268, LALMATI, NDGR 296, NDR 392, MADAK, CR 1002, RR 272-89, RR 366-4, NDR 97, MOTI, and NDR 2026) confined highly resistance and 8 rice germplasm (BHANTAPHOOL 2, KALANAMAK 2, NAGINA 22, SWARN SUB 1, SHUSK SAMRAT, NDR 118, MADHUKAR, and SWARN) confined moderately resistance respectively.
