3. Methods adopted to modify plants genetically for a better yield is called crop variety improvement.
4. It can be either done by hybridization or genetic engineering.
5. The objectives of crop variety improvement are as follows:

1. Increase the yield of plant products.
2. Improve the quality of food crops.
3. Produce biotic and abiotic resistant varieties.
4. Produce plants with a wide range of adaptability.
5. Impart desirable characteristics to crops.
6. Reduce the duration of maturity of crops.
