Question

A researcher wants to make a hybrid variety of a plant. Which among the following criteria he may consider to make the hybrid more vigorous?
1. Increase in quality
2. Increase in yield
3. Increase in size and number
4. Increase in biological efficiency
5. Greater resistance to disease and pest
6. Greater ecological amplitude/adaptivity

• A. 1 and 2 only
• B. 1, 2, and 3 only
• C. 4, 5 and 6 only
• D. 1, 2, 3, 4, 5, and 6

Answer 1

The correct option is D 1, 2, 3, 4, 5, and 6

Artificial hybridisation is the crossing of two different plants having complementary superior traits in order to obtain a superior variety.

It has been used by plant breeders for crop improvement programme The main purpose behind creating an artificial hybrid is to make a better variety of a plant to ensure better quality, more yield, increase in size and number of offspring, increase biological and reproductional efficiency, greater resistance to disease and pest and greater ecological amplitude to survive the harsh environment. So, basically all the statements given in the question can be considered by a breeder or researcher to perform hybridisation to make the hybrid have more vigour and be robust.
