Step 1: Understanding the Concept:
The question asks to identify a variety of apricot that is self-incompatible, meaning its flowers cannot be fertilized by their own pollen and thus require pollen from a different, compatible variety (a pollinizer) to set fruit.
Step 2: Detailed Explanation:
Let's examine the options:
\[\begin{array}{rl} \bullet & \text{1. Halman: This is a leading commercial cultivar of apricot, especially in the dry temperate regions of India like Ladakh. It is well-known to be self-incompatible and requires inter-planting with pollinizer varieties like Rakchakarpo or Suffaida for successful fruit set. } \\ \bullet & \text{2. Nari: This is another apricot cultivar, but it is not as famously self-incompatible as Halman. } \\ \bullet & \text{3. Charmagz: This is an apricot variety primarily grown for its sweet kernel, which is used as a dry fruit. It is generally self-fruitful. } \\ \bullet & \text{4. Turkey: This is a self-fruitful apricot variety. } \\ \end{array}\]
Therefore, 'Halman' is the correct answer.
Step 3: Final Answer:
Halman is a self-incompatible cultivar of apricot that requires a pollinizer.
