Steps of hybridisation are explained below:

(i) Varieties of plant with desirable characters are selected. These plants are genetically dissimilar.

There are two patterns of selection: mass selection and pure-line selection.

(ii) Pollens are collected from the male flower by the process of emasculation.

(iii) Collected pollens are transferred onto the stigma of female flower.

(iv) Stigma containing the pollen grains is bagged to avoid unnecessary pollination by other pollen grains.
