Paradigm Shifts in Research on Host Plant Resistance to Insect Pests uri icon


  • Conventional breeding in conjunction with molecular techniques and transgenic approaches have a great promiseto reduce pest associated crop losses, and accelerate the progress in developing cultivars with resistance toinsects. Although, considerable progress has been made over the past two decades in manipulating genes fromdiverse sources to develop plants with resistance to insect pests, deployment of molecular techniques for insectresistance, understand nature of gene action and metabolic pathways, but rapid and cost effective developmentand adoption of biotechnology-derived products will depend on developing a full understanding on the interactionof genes within their genomic environment, and with the environment in which their conferred phenotype interact.A good beginning has been made in developing genetic linkage maps of many crops, but the accuracy and precisionof phenotyping for resistance to insect pests remains a critical constraint in many crops. Improved phenotypingsystems will have substantial impact on both conventional and biotechnological approaches to breed for resistanceto insect pests, in addition to the more strategic research that feeds into these endeavors
