Explain how emasculation & bagging techniques help to achieve artificial hybridisation?

Emasculation technique
Emasculation technique

 Emasculation – The pollen and anthers are cut off from the flower,  so as to avoid self pollination

Bagging – Covering the emasculated flower by a bag to ensure that pollinating agents don’t reach the emasculated flower.

Pollen of desired type can be dusted on the stigma of emasculated flower.

Thus, artificial hybridisation can be achieved.
