Which of the following is necessary for improvement of the quality of crops? (1) Introduction (2) Hybridization (3) Selection (4) Segregation
- (a) 2, 3 and 4
- (b) 1, 2, 3 and 4
- (c) 1, 2 and 3
- (d) 2 and 3
Show the answer and explanation
Answer: (c) 1, 2 and 3
Introduction, hybridisation and selection are the classic plant-breeding methods.
Why the others are wrong
(a) Includes segregation, which is a genetic process, not a breeding method.
(b) Includes segregation.
(d) Drops introduction (bringing in new varieties).
The trap
Segregation happens during breeding, but it is not a method you apply.
🔒 Breeding methods: introduction, selection, hybridisation, mutation, polyploidy.
