A single variety of crop does not possess all the desirable characteristics. Thus, it is necessary to improve the crop variety. This is done to get better varieties of crops with the desired qualities. Two fundamental approaches are adopted to get the desirable characteristics in a single variety. These are:
Hybridization
Genetic engineering
Hybridisation is the crossing of two genetically dissimilar plants. It can be done between two species (interspecific), between two plants of same genera (intergeneric) and between different varieties of same species (intervarietal).
Genetic engineering: This helps to produce genetically modified crops. It is done by introducing a gene that would provide the desired characteristics.
