Question

how is artificial hybridisation useful to plants

Answer 1

The process of artificial hybridization of plants involves the following steps like emasculation.

Here the process of removing anthers or stamens or killing the pollen grains of a plant to be used as the female parent in a cross is called emasculation.

However, on the whole it is beneficial for raising better crop and helps the plant yield better.

Answer 2

Artificial hybridization is the process of using only the intended or the desired pollen grains for the process of fertilization.

There are processes involved in order to achieve this.

The processes are mainly aimed at :

1) Preventing self pollination

2) Preventing undesired pollen grains from being used in fertilization.

The processes are as follows:

1) emasculation - This involves cutting the anthers of a bisexual plant to encourage cross pollination.

2) Bagging - This involves covering the emasculated plant to prevent fertilization from undesired pollen. The desired pollen is then rubbed onto the stigma to allow fertilization.
