1.Hybridization may be defined as the process of mating two organisms belonging to two different species to create an organism possessing the qualities of both the organisms. The advantages of hybridization are:
1) They can increase the yield.
1) Two species combine to form the best of the organism eliminating the unwanted qualities of both the parent species.
2) They result in the formation of organisms which possess various qualities such as disease resistance, stress resistance etc.
The disadvantages of hybridization are:
1) The process of hybridization is quite expensive costing up to five times the value of the normal process.
2) They suffer more than the normal plants if not provided with the normal requirements.
2.Hybridization
Hybridization is the process in which two genetically dissimilar individuals (varieties) are purposely crossed to get a hybrid variety. In this way, characteristics from both the parent varieties can be obtained in the hybrid variety. This process is also known asplant breeding. Hybridization can be:
- Inter-specific, i.e., between two differentspeciesof a plant
- Inter-generic, i.e., between twogenera
- Inter-varietal, i.e., between different plant varieties
Genetic engineering
Genetic engineering is the process in which the gene for a particular character is introduced inside the chromosome of a plant cell (or individual). The introduction of this gene in the individual leads to the production of atransgenic plant.Such a transgenic plant exhibits the character of the newly introduced gene.
