In India, the release of a new crop variety consists of the following four major steps. Arrange the steps in sequence from the start to the last.
(A) Identification of the superior strains in the Annual Workshop of the specific crop
(B) Development of an improved strain of a particular crop
(C) Evaluation of the improved strain in multilocation trial
(D) Release and notification of the crop variety by the variety release committee

Show Hint
1. Create/develop the strain (B).
2. Test it across India (C).
3. Identify it as superior in a workshop (A).
4. Formally release and notify it by the committee (D).
- (B), (A), (C), (D).
- (B), (C), (A), (D).
- (B), (A), (D), (C).
- (C), (B), (D), (A).
The Correct Option is B
Solution and Explanation
The development and release of a new crop variety in India is a highly structured, multi-step process coordinated under the All India Coordinated Research Projects (AICRP) of the ICAR.
Step 2: Detailed Explanation:
Let us arrange the steps of crop variety release in their correct chronological sequence:
-
Step 1: (B) Development of an improved strain of a particular crop:
The plant breeder first utilizes various breeding methods (such as hybridization, pedigree selection, or mutation) to develop a genetically superior, stable strain or line of a crop.
- (C) Evaluation of the improved strain in multilocation trial:
The developed strain is entered into multi-location yield trials (coordinated testing across different agro-climatic zones under the AICRP system) for 3 or more years to assess its yield, disease resistance, and adaptability.
-
Step 2: (A) Identification of the superior strains in the Annual Workshop:
Based on the multi-location trial data, outstanding strains are identified and officially proposed for release during the Annual Workshop of the crop-specific AICRP.
-
Step 3: (D) Release and notification of the crop variety by the variety release committee:
The identified strain's proposal is submitted to the Central Variety Release Committee (CVRC) or State Variety Release Committee (SVRC).
Upon approval, the variety is officially released and notified in the Gazette of India, making its certified seed eligible for commercial seed production and sale.
Therefore, the correct chronological sequence is: (B) $\rightarrow$ (C) $\rightarrow$ (A) $\rightarrow$ (D).
Step 3: Final Answer:
The correct chronological sequence of steps is (B), (C), (A), (D).
