Question
Define plant breeding? Describe the various methods of plant breeding.
✓
Answer
Plant breeding means production of new varieties or strains by a programme of artificial selection spanning several generations of the organism concerned.
It involves hybridization and mutation breeding:
-
Hybridisation: It involves the crossing between genetically dissimilar plants to produce a new kind. Crossing may be between two different varieties (intervarietal cross-breeding) or between the two different species of the same genus (inter specific cross-breeding) and between different genera (intergeneric cross-breeding).
-
Mutation breeding: The breeding that takes place through various mutagens.
