Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Hybrid seed production in vegetable crops is made commercially viable by utilizing specific pollination-control mechanisms, such as male sterility, gynoecy, and self-incompatibility.
These biological systems ensure 100% cross-pollination without the need for manual emasculation.
Step 2: Detailed Explanation:
Let us match the commercial vegetable hybrids with their respective genetic production systems:
A. Pusa Nayanjyoti: This is an orange-colored carrot hybrid developed by IARI, which utilizes the Cytoplasmic Male Sterility (CMS) system for commercial seed production. Thus, A matches with II.
B. Pusa Hybrid-2 (Cauliflower): This early-maturing cauliflower hybrid developed by IARI utilizes Self-Incompatibility (SI) alleles to ensure cross-pollination between the two parental lines. Thus, B matches with III.
C. Pusa Seedless Cucumber-6: This greenhouse cucumber hybrid utilizes a Gynoecious (purely female flowering) line as the seed parent to produce seedless fruits parthenocarpically. Thus, C matches with IV.
D. CH-1 (Chilli Hybrid 1): Developed by PAU, Ludhiana, this famous chilli hybrid utilizes the Genic Male Sterility (GMS) system (specifically the ms-10 gene) to eliminate hand-emasculation. Thus, D matches with I.
Combining these matches gives: A - II, B - III, C - IV, D - I.
Step 3: Final Answer:
The sequential match corresponds to option (D).
