HYBRIDIZATION
Definition:
• The combining or crossing of two genetically dissimilar plants to create a hybrid is called as Hybridization.
• It is a process through which hybrids are obtained.
Applications of Hybridization:
Procedure of Hybridization: It involves the following steps:
1. Selection of parents
2. Emasculation
3. Bagging
4. Tagging
5. Crossing
6. Harvesting and storing the F, seeds
7. Raising the F1 generation.
