Step 1: Understanding the Concept:
Breeding programs in mango aim to combine traits like regular bearing, high yield, dwarf canopy, sweet fiberless pulp, and longer shelf life through hybridization.
Step 2: Detailed Explanation:
'Arka Suprabhath' (H-12) is a double-cross mango hybrid released by the Indian Institute of Horticultural Research (IIHR), Bengaluru.
It is developed by crossing:
- Female Parent: Amrapali (Dashehari $\times$ Neelum)
- Male Parent: Arka Anmol (Alphonso $\times$ Janardhan Prasad)
The parentage is designated as Amrapali $\times$ Arka Anmol.
This variety is characterized by regular bearing, dwarf stature (ideal for high-density orchards), and high-quality fruit with firm pulp and a high TSS of about $22^\circ\text{Brix}$.
Step 3: Final Answer:
Arka Suprabhath is a cross between Amrapali and Arka Anmol.
