Step 1: Understanding the Concept:
Brinjal (Solanum melongena) varieties are classified into different categories based on their fruit shape: round, oblong, or long.
Step 2: Detailed Explanation:
- "Arka Shirish" produces long, green, and tender fruits.
- "Pusa Bhairav" produces long, purple fruits (highly resistant to Phomopsis blight).
- "Punjab Sadabahar" is a popular variety that produces long, dark purple fruits.
- "Pant Rituraj" is a round-fruited variety.
Since multiple options are technically long-fruited, we look at the variety specifically released as a standard long-fruited variety across national trials.
Among these, Punjab Sadabahar is a very famous long-fruited cultivar.
Step 3: Final Answer:
Punjab Sadabahar is a long-fruited variety, hence it is NOT round-fruited.
