Q- Explain any one method of crop production which ensures high yield.
Answer:- Hybridisation is one of the best method of crop production which ensures high yield.
Hybridisation in animals is known for over 2000 years. Cotton mather (1716) noticed first artificially plant hybrid in corn. Joseph kolreuter (1760), a german botanist carried out first hybridization experiment in tobacco.
Hybridisation is the crossing of two plants differing from each other genotypically in one or more traits.
