The technique applied for obtaining improved varieties of crops is called plant breeding. The prime objective of plant breeding is crop improvement, that is, to improve the characteristics of plants so that the plant is agronomically superior. Crop variety improvement is necessary :
1. to increase the yield of crop production
2. to produce disease resistant crops
3. to increase the nutrient quality of the crops
4. India’s population is increasing alarmingly, so to meet the ever-increasing demand for food, we need to improve crop varities for food production.
The techniques for crop improvement involve steps for selection of plants with desirable characteristics (selection), crossing them to combine all these characteristics in the off springs (hybridization) and then multiplying (breeding -conventional, mutation, tissue culture, genetic engineering) these to make it available to the farmers for commercial use.
