Question
Explain various steps in hybridization of crop plants.
✓

Answer

The three steps involved in hybridization are:
  1. Introduction: This refers to the transportation of crop plants from the place of cultivation to the place where they were grown earlier.
  2. Selection: This process involves the selection of most desirable offspring of a variety of plant for controlled propagation.
  3. 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).
