The domain plant tissue culture & vegetative propagation impartshands-on experience to the students to work and focus on asexual propagation techniques including micro-propagation (plant tissue culture techniques), vegetative propagation like grafting, cuttings usage, etc. The process of plant production/plant multiplication which can be carried out byusing our own plant material with less investment, through which the students get industry-academia experience. Commercial cultivation of crops mainly aims at genetic fidelity,enhanced productivity, disease-free/resistant plants and plants with desired characteristics.The two major applications of the domain is to conserve the germplasm varieties and maintain genetic fidelity among the plants produced in vitro. Such materials are maintained for their original characteristics can also be explored for research and development as well as breeding programs.
