Choose the correct answer from the options given below:

Show Hint

To remember coconut varieties, associate 'Chandra' followed by a simple noun (like 'Kalpa') or local names (like 'Pratap') with selections, while 'Chandra' followed by 'Sarkara' or names like 'Kera Sree' and 'VHC' are hybrids. WCT and COD are the primary parents for Indian coconut hybrids.

The Correct Option is B

Solution and Explanation

Step 1: Understanding the Concept:
In coconut (Cocos nucifera) breeding, genetic improvement is achieved through selection and hybridization.
Hybrids are produced by crossing Tall and Dwarf varieties to exploit heterosis (hybrid vigor).
Selections represent superior genotypes isolated directly from local or introduced germplasm based on physical performance.

Step 2: Detailed Explanation:

Let us analyze the breeding origins of each cultivar to classify them:
A. VHC 3 (Veppankulam Hybrid Coconut 3): This is a hybrid developed by crossing East Coast Tall (ECT) as the female parent and Malayan Orange Dwarf (MOD) as the male parent (ECT $\times$ MOD).
Released by Tamil Nadu Agricultural University, it is highly valued for its high nut yield and oil content.
B. Chandra Kalpa: This is a selection from the Laccadive Ordinary tall cultivar, released by the Central Plantation Crops Research Institute (CPCRI). It is not a hybrid.
C. Chandra Sarkara: This is a hybrid developed by crossing Chowghat Orange Dwarf (COD) and West Coast Tall (WCT) (COD $\times$ WCT). It is known for its early bearing and high yield under ideal management.
D. Kera Sree: This is a hybrid developed by crossing West Coast Tall (WCT) and Chowghat Orange Dwarf (COD) (WCT $\times$ COD). It is highly productive and suitable for diverse agro-climatic conditions.
E. Pratap: This is a selection from the local Benaulim tall variety of Goa and Maharashtra, released for its tolerance to drought and high wind speeds. It is not a hybrid.
Therefore, only A (VHC 3), C (Chandra Sarkara), and D (Kera Sree) are coconut hybrids, whereas B and E are selections.

Step 3: Final Answer:

Since VHC 3, Chandra Sarkara, and Kera Sree are hybrids, while Chandra Kalpa and Pratap are selections, the correct option is (B).
