A hybrid variety of pigeon pea is

Question

Accepted Answer

Here is a detailed explanation for the given question:

**Correct Answer: Option 2 (I.C.P.H. - 8)**

**Explanation for Option 2 (I.C.P.H. - 8) being correct:**
I.C.P.H. - 8 stands for International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) Pigeonpea Hybrid - 8. It is a landmark variety as it was the **world's first commercial hybrid variety of pigeon pea (arhar/tur)**, released in India in 1991. Hybrids are developed by crossing two genetically distinct parent lines to combine desirable traits and often exhibit hybrid vigor (heterosis), leading to higher yields and improved performance compared to conventional varieties. I.C.P.H. - 8 is known for its high yield potential, disease resistance, and adaptability, making it a true hybrid variety of pigeon pea.

**Explanation for other options being incorrect:**

*   **Option 1 (U.P.A.S. - 120):** U.P.A.S. - 120 is a well-known and widely cultivated variety of pigeon pea. However, it is a **conventional (pure line) variety**, not a hybrid. It is particularly recognized for its early maturity and suitability for specific cropping systems, but it was developed through selection from pure lines, not through hybrid breeding.

*   **Option 3 (Bahar):** Bahar is another very popular and widely grown variety of pigeon pea, especially in North India. It is known for its late maturity and high yield potential under specific conditions. Like U.P.A.S. - 120, Bahar is a **conventional (pure line) variety**, developed through traditional breeding methods, and not a hybrid.

*   **Option 4 (I.C.P.L. - 87):** I.C.P.L. - 87, also known as 'Pragati', is a significant variety developed by ICRISAT. The 'L' in I.C.P.L. stands for 'Line', indicating that it is an **improved pure line variety**, not a hybrid. It is known for its early maturity and resistance to wilt disease, making it a valuable conventional variety, but it does not possess the genetic makeup of a hybrid.
