Arrange the steps involved in breeding a crop for a new genetic variety in sequence.
A. Selection and testing of superior recombinants
B. Evaluation and selection of parents
C. Collection of variability
D. Testing release and commercialisation of new cultivars
E. Cross hybridisation among selected parents
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → C → B → E → A → D
C. Collection of variability — first. All the wild relatives and cultivated varieties of the crop are collected; this germplasm collection is the raw material of breeding.
B. Evaluation and selection of parents — second. The collected plants are tested, and those with the desired characters are chosen as parents.
E. Cross hybridisation among selected parents — third. The chosen parents are crossed so that their good characters come together in one plant.
A. Selection and testing of superior recombinants — fourth. From the hybrid progeny, the plants that carry the desired combination are selected and self-pollinated for several generations.
D. Testing, release and commercialisation of new cultivars — last. The new lines are grown in farmers' fields for at least three seasons and compared with the best local variety before release.
