Emasculation is a plant breeding technique where the anthers are removed manually with the help of forceps to prevent self fertilization.
This is done for artificially hybridizing the plant with a desired anther and stamen interaction to produce desired plant results.
A plant breeder employs this technique to produce desired plant hybrids and prevent self fertilization.
Final Answer:
Emasculation is a type of artificial hybridization where the anther is removed before self pollination.
A plant breeder does this before the plant breeding time to produce desired hybrids.
