Performance of some anise genotypes under tokat ecological conditions

The study aimed to determine the performance of some anise genotypes under Tokat's ecological conditions. The research was conducted during the 2023 growing season in Tokat-Kazova ecological conditions according to the Randomized Complete Block Design with three replications. Materials consisted of 10 different populations collected from various regions of Turkey and three registered varieties. The study evaluated findings regarding emergence time, flowering time, maturation time, plant height, number of branches per plant, number of fruiting branches per plant, number of umbels per plant, number of fruits per umbel, seed yield per plant, thousand-seed weight, seed yield, essential oil ratio, and essential oil yield. Among the examined traits, thousand-seed weight was found to be statistically insignificant, whereas all other parameters were determined to be highly significant (p<0.01). Emergence time ranged from 30-33 days, flowering time from 65-71 days, and maturation time from 97-102 days. Plant height varied from 57.60 to 69.53 cm, branch number per plant from 4.50 to 6.70, fruiting branch number per plant from 3.90 to 5.90, number of umbels per plant from 4.20 to 7.90, fruits per umbel from 367.97 to 698.87, seed yield per plant from 0.89 to 2.59 g, thousand-seed weight from 2.07 to 2.66 g, seed yield per decare from 28.00 to 67.00 kg/da, essential oil ratio from 1.62% to 2.59%, and essential oil yield from 0.46 to 1.51 l/da. The population from Syria exhibited the highest seed yield (67.00 kg/da) and essential oil yield (1.51 l/da). According to the study results, the Syrian population and Altın 8 and Ege 53 variety stood out in terms of seed and oil yield.
