Concept-

• A wide range of fungal, bacterial, and viral pathogens, affect the yield of cultivated crop species, especially in tropical climates.
• Crop losses can often be significant, up to 20-30 per cent, or sometimes even total.
• In this situation, the breeding and development of cultivars resistant to disease enhance food production.
• This also helps reduce the dependence on the use of fungicides and bacteriocides.

Explanation-

• Resistance of the host plant is the ability to prevent the pathogen from causing disease and is determined by the genetic constitution of the host plant.
• Before breeding is undertaken, it is important to know about the causative organism and the mode of transmission.
• Some of the diseases caused by-
  • Fungi are rusts, e.g., brown rust of wheat, red rot of sugarcane, and late blight of potato.
  • Bacteria – black rot of crucifers.
