Resistance breeding and it’s advantage

Resistance breeding

The capacity of insects to attack the host or a specific component of the host is often specialised. Every kind of host can be harmed or attacked by an insect. The traits that allow a plant to avoid, withstand, or recover from an insect assault under circumstances that would cause more harm to other plants of the same species are included in the category of plant resistance.

Resistance is a plant’s inherited quality that affects how much harm the insect ultimately does. In other words, plant resistance is described as the collective heritable trait that a plant species develops in groups or individually to decrease the likelihood that an insect species, race, biotype, or individual would successfully utilise that plant or a host. The relative phrase “degree of resistance” is determined by using a susceptible cultivar of the same plant species as a reference.

Specific host plants’ levels of resistance might range from complete immunity to high sensitivity. Resistance is any level of host response below immunity. In the event of abiotic stress, the plants with the desired characteristics will be employed as donors in breeding programmes, and the amino acids or enzymes related to tolerance or resistance to variables such as salinity, drought, and other factors will be determined.

Advantages of resistant breeding

  • Farmers don’t need to spend extra money on plant protection chemicals when using resistant types.
  • Fungicides and other pesticides have a lasting impact, so it is a prudent precaution.
  • Compared to other methods of disease and pest management, it is more successful.
  • With any other method of disease management, it is difficult to cover a greater region when dealing with airborne infections.
