Pusa RH 10 is a hybrid variety of .....
Show Hint
Pusa RH 10 was the first commercial Basmati rice hybrid.
Remember its parental combination: Pusa 3A \( \times \) PRR 78.
It revolutionized aromatic hybrid rice breeding by proving that high yield and premium grain quality can be combined in a single hybrid.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Hybrid crop technology leverages heterosis (hybrid vigor) to significantly increase grain yield, resource-use efficiency, and resilience against environmental stresses compared to pureline varieties.
Step 2: Detailed Explanation:
Pusa RH 10 is a highly famous aromatic hybrid variety of Rice (specifically Basmati rice).
It was developed by the Indian Agricultural Research Institute (IARI), New Delhi, and released in 2001.
Pusa RH 10 is recognized as the world's first superfine grain aromatic hybrid rice.
It was developed using the Cytoplasmic Male Sterility (CMS) three-line breeding system (comprising A, B, and R lines).
The parental lines involved in the cross are Pusa 3A (male sterile line) and PRR 78 (restorer line).
This hybrid offers several notable advantages:
- Yield increase: It yields approximately \( 1.0 \) to \( 1.5 \) tonnes per hectare more than traditional aromatic varieties.
- Early maturity: It matures within 115 days, which is significantly faster than standard Basmati lines, facilitating better crop rotations.
- High quality: It maintains premium grain elongation, excellent aroma, and non-sticky cooking characteristics.
Step 3: Final Answer:
Pusa RH 10 is a hybrid variety of Rice.
