Types of hybridization

Inter-varietal hybridization

• The parents involved in hybridization belong to the same species. There may be two strains, varieties or races of the same species. It is also known as intraspecific hybridization.
• The intravarietal crosses may be simple or complex depending upon the number of parents involved.
• Simple cross: In a simple cross, two parents are crossed to produce the F1

F1

• Complex cross: More than two parents are crossed to produce the hybrid.
