Explain various steps in hybridization of crop plants.
The three steps involved in hybridization are:
(i) Introduction - This refers to the transportation of crop plants from the place of cultivation to the place where they were grown earlier.
(ii) Selection - This process involves the selection of most desirable offspring of a variety of plant for controlled propagation.
(iii) 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 crossbreeding).
