Abstract

One hundred-seventeen eggplant genotypes were screened for field resistance to the leafhopper at vegetative and reproductive stages and resistance to the eggplant fruit borer at harvest time. The different eggplant accessions were planted at Block B Lot-12, IPB Demo Area, Central Experiment Station (CES), Pili Drive, UPLB during the 2000 and 2001 screening trials. Plants were maintained following standard cultural practices in eggplant production. Data on insects, bacterial wilt and plant parameters were taken at different sampling periods. Leafhopper infestation at the CES-UPLB followed the same patterns as that observed at the CES-PhilRice, Maligaya, Muñoz, Nueva Ecija. Leafhopper population started to build up at 45 DAT, reached its peak at 60 DAT and gradually declined as the plant matured. Results revealed that 28 entries, mostly wild relatives of eggplant were resistant; 69 entries moderately resistant and 15 intermediate. 544 white was the most susceptible to leafhopper. Entries EG 203, A 300, Acc 544 White, SRO2 and Batangas Long Purple were moderately resistant while Acc. 618, Abar and Sinampedro were susceptible to the fruit borer. On the other hand, 42 entries were resistant while 19 entries were susceptible to bacterial wilt. A300, SRO2, Acc 610, Acc 615, EG 203 and Abar are promising varieties with resistance to pests. Acc 6, 483, 492, 508, 513 and 671, wild relatives of eggplant, can be used as sources of resistance to the above pests.
