Define hybridisation. List the steps to be followed for obtaining seeds of a hybrid variety.
Hybridisation is the process of crossing two genetically different ‘individuals’ to obtain a new ‘individual’ (hybrid) exhibiting desirable characteristics.
Steps to be followed for obtaining seeds of a hybrid variety are as follows:
Step 1: Two varieties of plants, say A and B, of desired characteristics are chosen.
Step 2: Anthers from plant ‘A’ are removed. This process is called emasculation.
Step 3: Anthers from plant ‘B’ are taken and its pollen are dusted on stigmas of ‘A.
Step 4: Stigmas of ‘A’ are then covered by paper bags.
Step 5: By such cross breeding of two desired varieties, seeds of a hybrid variety can be obtained.
