Types of Hybridization

• Inter-varietal Hybridization / Intra specific: Parents involved in hybridization belongto the same species. They may be two strains, varietiesor races.
• Varietal crosses may be simple crosses or complex crosses

  a.Simple crosses: Two parents are crossed to produce F1(A XB)

  b. Complex crosses: More than two parents are crossed to produce the hybrid (AXB) X C X F1
