‘Narma’ is a variety of which crop?

Many Rajasthan/agriculture General-Knowledge questions test whether a named cultivar or a crop's popular local name can be correctly matched to its parent crop. 'Narma' is the widely used north-Indian/Rajasthani name for American cotton (Gossypium hirsutum); flagship releases carrying this name, such as 'Bikaneri Narma', are grown across the Sriganganagar-Hanumangarh cotton belt of northern Rajasthan.

No wheat, rice, or maize variety register - including the ICAR-IIWBR national wheat-variety compendium and the RARI Durgapura crop-variety release lists - records any cultivar called 'Narma', so the wheat, rice, and maize options are not supported by the varietal-naming record.

Cross-checking against independent Rajasthan-GK exam sources confirms the same question ('Narma' is a variety of which crop? - Wheat / Rice / Cotton / Maize) is answered Cotton, matching the regional cotton-naming convention.

So the correct answer is Cotton.
