Step 1: Understanding the Concept:
Coconut breeding programs at the Central Plantation Crops Research Institute (CPCRI) focus on developing high-yielding, resilient hybrids.
These hybrids are selected for superior yield, tender water quality, and environmental tolerance.
Step 2: Detailed Explanation:
"Kalpa Samrudhi" is a premium hybrid coconut variety developed and released by CPCRI.
- Statement (A): It is a dual-purpose hybrid suitable for both tender coconut water and copra production.
It yields about 4.35 tonnes of copra per hectare per year. Thus, (A) is correct.
- Statement (B): This variety is highly drought-tolerant, performing well in areas with water scarcity. Thus, (B) is correct.
- Statement (C): Kalpa Samrudhi possesses high nutrient-use efficiency, enabling it to produce stable yields under resource-limited soil conditions. Thus, (C) is correct.
- Statement (D): It is developed from a cross between Chowghat Green Dwarf (CGD) as the female parent and West Coast Tall (WCT) as the male parent.
This cross (CGD \( \times \) WCT) combines the early flowering of the dwarf parent with the high yield and vigor of the tall parent. Thus, (D) is correct.
Since all four statements are scientifically accurate, option (C) is the correct choice.
Step 3: Final Answer:
All the given statements (A, B, C, and D) about Kalpa Samrudhi are true.
