Abstract: (7710 Views)
To evaluate the genetic variations in eleven fennel populations in Iran, 55 accessions were analyzed by SRAP markers. Twelve primer combinations produced 171 polymorphic bands. The cumulative dendrogram delineated fennel accessions into five major groups in accordance to the geographical regions from which the populations were originated. About 43.57% of total genetic variation was detected among the populations, while 56.43% of total variation were observed within the populations. The studied populations showed high genetic differentiation (Gst= 0.52) and low gene flow (Nm= 0.46). Among the studied populations, Yazd and Kerman accounted for the highest values of PPB (%), Shanon index (I), and heterozygosity. The self-pollinated seeds were in the range of 2.01% in Paveh-2 to 9.24% in Isfahan-2 accessions. The essential oil content ranged from 0.62% in Isfahan-3 to 2.21% in Tabriz-3. Generaly, the dwarf populations viz., Tabriz and Paveh, had higher essential oil yield and their pollination was less affected by environmental factors than the average.
