Assessment of biophysical and biochemical bases of resistance in brinjal against major insect pests

Abstract

Brinjal (Solanum melongena L.) is widely grown vegetable of tropical and subtropical parts of the world. Numerous factors are accountable for the short productivity of brinjal, as it is subjected to attack by number of insect pest right from nursery stage till harvesting. In this process the adaption of insect pests to host plants involved behavioral and metabolic changes which enabled insect to cope with the physical and chemical defense systems of plants during evolution. But, Considerable progress has been made in identification and development of crop cultivars with resistance to the major pests in brinjal crop. Host plant resistance (HPR) mechanism is a significant, effective, economical and environmental friendly process in for major insect pest control. There is a need to use breeding approaches to transfer of resistance genes into high-yielding cultivars with adaptation to different agroecosystems. Resistance to insects should form one of the criteria to release varieties and hybrids for cultivation by the farme.
