Plant Breeding for Developing Resistance to Insect Pests
- Another major cause for large scale destruction of crop plant and crop produce is insect and pest infestation.
- Insect resistance in host crop plants may be due to morphological, biochemical or physiological characteristics.
- Hairy leaves in several plants are associated with resistance to insect pests, e.g, resistance to jassids in cotton and cereal leaf beetle in wheat.
- In wheat, solid stems lead to non-preference by the stem sawfly and smooth leaved and nectar-less cotton varieties do not attract bollworms.
- High aspartic acid, low nitrogen and sugar content in maize leads to resistance to maize stem borers.
- Breeding methods for insect pest resistance involve the same steps as those for any other agronomic trait such as yield or quality and are as discussed in conventional breeding.
- Some released crop varieties bred by hybridisation and selection, for insect pest resistance are given in Table below:
