Mechanisms of resistance in brinjal (Solanum melongena L.) to whitefly Bemisia tabaci (Gennadius)

摘要

Ten brinjal accessions including two wild accessions were evaluated in glasshouse for their level of resistance and the mechanisms of resistance against Bemisia tabaci (G.). The morphological characters viz. trichome density, length, breadth and thebiochemical characters viz. solanine phenols, sugars and pH play a deferential role in the preference of feeding. The accessions TS 00052 and Arka neelakanta were found to have less population and fewer trichome with higher amount of solanine, phenols, lower levels of sugars and pH. The wild type accessions manifested a high level of resistance to B. tabaci.
