Arrange the steps of traditional plant breeding in sequentially.
(A) Evaluation of hybrids
(B) Emasculation of selected parents
(C) Screening of germplasm
(D) Hybridisation of selected parents
(E) Release of hybrid variety
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (C), (B), (D), (A), (E)
Breeding for disease resistance begins with screening germplasm (C), then emasculation (B) and hybridisation (D) of selected parents, evaluation of hybrids (A), and finally release of the variety (E).

NCERT Extract (Pre-rationalised edition, Chapter 9, Strategies for Enhancement in Food Production):
Plant Breeding for Disease Resistance – “… The conventional method of breeding for disease resistance is that of hybridisation and selection. It’s steps are essentially identical to those for breeding for any other agronomic characters such as high yield. The various sequential steps are : screening germplasm for resistance sources, hybridisation of selected parents, selection and evaluation of the hybrids and testing and release of new varieties.”
