Question

Which of the following methods can be used for improving crop variety?

• A. Usage of more fertilizers
• B. Hybridisation
• C. Supplying more water to plants
• D. Allowing plant to grow in forests

Answer 1

The correct option is B Hybridisation

Crop variety can be improved by hybridisation which involves crossing between genetically dissimilar plants to produce plants with superior traits. Crops can also be improved by using genetic engineering in which a desired gene is introduced into a particular plant. This technique aims at specific and targeted changes in the plant.
