Abstract
AbstractInducing insect resistance in the host plant is one of the important components of host plant resistance. Resistance can be induced artificially in the plant system by application of external elicitors such as fertilizers, herbicides, plant hormones, and herbivores. Inducing insect resistance using mutagens produce resistant crop plants with long-lasting resistance potential by heritable changes in their genes. Considering this, promising sesame germplasm was selected as a model system to study the induction of resistance through mutation breeding approaches. There were many successful attempts to increase the oil quality, yield potential, shatter resistance, and disease resistance using mutation breeding but attempts to increase insect resistance in crop plants are scarce. Hence, experiments were conducted to induce webworm resistance in sesame using physical and chemical mutagens at the Department of Entomology, Faculty of Agriculture, Annamalai University, Tamil Nadu. In the field experiment, varieties mutagenized using physical and chemical mutagens were found resistant against webworm. The variation between the mutagenized varieties and non-mutagenized control parents in biophysical, biochemical, and yield attributes were significant. Mutagenized varieties showed higher number of trichomes, higher level of phenol and yield than the control ones.KeywordsGeneticsInduced resistanceMutagensSesamum
