Bushy, highly branched plant type (40-45 branches per plant). Exceptional vegetative vigour combined with good seed yield. High market value for commercial cultivation.

Pratapgarh district, Rajasthan (traditional farming communities) · Farmer-maintained desi landrace; later selected and improved at ICAR-NRCSS for AA-1 development · Indigenous cultivar with centuries of cultivation history; formal selection began 1970s-1980s

Original farmer landrace from which Ajmer Ajwain-1 was derived through recurrent selection. Represents the genetic foundation of modern improved varieties. Moderate yield but excellent aromatic quality. Farmer-selected over generations for local market preferences.

Bari Sadri, Chittorgarh district, Rajasthan (traditional farming communities) · Farmer-maintained desi landrace; collected and improved by ICAR-NRCSS for AA-73 selection · Indigenous landrace with long cultivation history; formal collection and selection began 2001

Renowned regional desi type from Chittorgarh, historically prized for bold seeds and aromatic quality. Selected material led to AA-73, now a high-yielding variety. Represents genetic diversity within Rajasthan's ajwain germplasm.

Gujarat state, particularly Unjha, Mehsana, and Sabarkantha districts (traditional spice-growing regions) · Farmer-maintained desi cultivars; some improved at SDAU for GA-1 and GA-3 varieties · Indigenous cultivar with centuries of cultivation; formal improvement began 1990s at SDAU

Foundation germplasm for Gujarat's modern ajwain varieties. Unjha region—Asia's largest spice market since 1954—traditionally famous for ajwain trading and seed selection. Farmer-selected for bold seeds, good aroma, and market quality. Represents 33% of India's national ajwain production.
