Show Hint

Many modern IARI mango hybrids (like Pusa Lalima, Pusa Shreshth, and Pusa Pratibha) use 'Sensation' as a parent because it consistently passes down its attractive, bright red peel color.
  • Pusa Lalima - Pusa Peetamber - Arunika - Pusa Shreshth
  • Pusa Shreshth - Pusa Lalima - Arunika - Pusa Peetamber
  • Pusa Shreshth - Arunika - Pusa Peetamber - Pusa Lalima
  • Pusa Shreshth - Pusa Lalima - Arunika - Pusa Peetamber

The Correct Option is B

Solution and Explanation

Step 1: Understanding the Concept:
This question focuses on the pedigree and parentage of mango (*Mangifera indica*) hybrids developed by the Indian Agricultural Research Institute (IARI) in New Delhi.

Step 2: Detailed Explanation:

Let us analyze each cross combination and identify its resulting hybrid:
(A) Amrapali $\times$ Sensation:
This cross was made to combine the dwarf, regular-bearing habit of 'Amrapali' with the attractive red peel color of 'Sensation.'
The resulting hybrid is Pusa Shreshth.
(B) Dashehari $\times$ Sensation:
This cross was made to introduce attractive red color into the popular North Indian cultivar 'Dashehari.'
The resulting hybrid is Pusa Lalima.
(C) Amrapali $\times$ Vanraj:
This cross combined 'Amrapali' with the colorful South Indian variety 'Vanraj.'
The resulting hybrid is Arunika, which is known for its dwarf growth habit and bright red blush.
(D) Amrapali $\times$ Lal Sundari:
This cross yielded Pusa Peetamber, a regular-bearing, high-yielding hybrid variety.
Let us match this with the sequential options:
- (A) Amrapali $\times$ Sensation $\rightarrow$ Pusa Shreshth
- (B) Dashehari $\times$ Sensation $\rightarrow$ Pusa Lalima
- (C) Amrapali $\times$ Vanraj $\rightarrow$ Arunika
- (D) Amrapali $\times$ Lal Sundari $\rightarrow$ Pusa Peetamber
This sequence matches the order: Pusa Shreshth -- Pusa Lalima -- Arunika -- Pusa Peetamber.

Step 3: Final Answer:

The correct sequence of mango varieties based on their parentage is Pusa Shreshth - Pusa Lalima - Arunika - Pusa Peetamber.
This corresponds to Option (B).
