A number of plant characteristics are known to render the cultivars less suitable or unsuitable for feeding, oviposition and development of insect pests. Broadly, these characteristics can be classified into two categories, i.e., biophysical and biochemical. 1. Biophysical Bases: The plant resistance is controlled by several morphological factors like remote factors, e.g., colour, shape, size, […]

Breeding Programme for Plant Resistance to Insects | Pest Management
Article shared by :
The first requirement of a breeding programme is the need and potential for plant resistance to insects within the pest management and cropping system. This will determine the type and level of resistance required, which in turn, will depend upon the pest biology and the production and commercial requirements for the crop. For example, if […]
