Abstract

Fourteen ajwain genotypes were evaluated at College of Horticulture, Bengaluru, Karnataka, India, from October 2019 to April 2020 in-order to identify suitable ajwain genotype for Eastern dry zone of Karnataka. The experiment was laid out in randomised complete block design and Fisher’s method of data analysis was used. Evident differences among ajwain genotypes in days to first flowering, 50 % flowering, days to maturity, number of umbels per plant, number of umbellet and seeds per umbel, seed yield per plant, per plot and per hectare, harvest index and test weight confirms the presence of variability among them. The genotype AA-93 registered minimum number of days to first flower appearance (53.00 days), days to 50 per cent flowering (65.00 days) and days for umbel formation (78.67 days). The maximum and minimum number of umbels per plant was registered in the genotype GA-1 (207.20) and Lam Sel-1 (99.33), respectively. The number of umbellet per umbel was maximum in the genotype AA
