What to Focus On

  • Plant breeding improves crop plants through genetic changes.
  • It aims to produce new varieties with better traits.
  • It combines knowledge from genetics, botany, and agriculture.

  • Develop high-yielding crop varieties.
  • Improve quality and resistance to diseases and pests.
  • Create drought-tolerant and stress-resistant crops.

  • Introduction: Bringing high-yielding varieties from one region to another.
  • Selection: Choosing the best plants based on their traits.
  • Hybridization: Crossing two genetically different parents to produce superior offspring.

Common Mistakes to Avoid

Hybridization always results in a new species.

Mutation breeding only uses natural mutations.

Pure line selection can be used for cross-pollinated crops.

Memory Tips

Five Methods of Plant Breeding: Introduction, Selection, Hybridization, Mutation Breeding, Polyploidy Breeding

Hybridization Procedure: Selection of Parents → Emasculation → Bagging → Artificial Pollination

Emasculation: Removal of anthers from bisexual flowers to prevent self-pollination

Heterosis or Hybrid Vigour: F1 hybrids are superior to parents
