Phytochemical variability and seed yield in three synthetic cultivars of bitter fennel (Foeniculum vulgar var. vulgare).

Bitter fennel, hereafter just called fennel, is an ancient medicinal plant from Apiaceae family, native to Mediterranean region. Metabolites derived from this plant are used in food, beverage, and pharmaceutical industries as curative and flavoring agents. These metabolites are extracted from the seeds, and there is an increasing demand for fennel seeds. Developing synthetic cultivars as a classical breeding approach can be a cheap and relatively fast way to increase yield in fennel, especially since synthetic cultivars are more tolerant in harsh and unstable environments. This study was conducted to evaluate phytochemicals, as well as seed yield of eleven fennel genotypes including three newly developed synthetic cultivars (early, medium, and late maturity) and eight of their elite parents. Compared to the early maturity synthetic cultivar and all the eight elite parents, medium and late maturity synthetic cultivars had the higher seed yields (267 and 261 gr/m2, respectively), and essential oil yields (5.2 and 4.6 cm3/m2, respectively). In total, Gas Chromatography Mass Spectrometry identified 23 compounds in essential oil of the eleven genotypes, with trans-anethole (%34-%78), limonene (%5-%13), methyl chavicol (%1-%39), and fenchone (%6-%13) as the major ones. The highest percentage of trans-anethole in total essential oil content belonged to one of the early maturity parents (Fasa) and to the medium maturity synthetic cultivar (%79 and %73, respectively). High Performance Liquid Chromatography (HPLC) coupled with Photo Diode Array (PDA) showed that major components of extracts from these fennel genotypes are ferulic acid (%1-%4.4), salicylic acid (%0.8-%6.8), caffeic acid (%1.3-%6.2), coniferyl alcohol (%0.4-%2.2), p-coumaric acid (%1.2-%6.4), sinapyl alcohol (%1.7-%9), ascorbic acid (%22.1-%70), and chlorogenic acid (%3.2-%43.1). Our result indicated that these fennel synthetic cultivars have the potential of higher production of valuable fennel derived metabolites. Our result indicated that compared to the elite parents, fennel synthetic cultivars have the potential of producing higher amounts of seed yield, and valuable fennel derived metabolites.
