Abstract:
To evaluate the genetic variations in eleven fenne
l populations in Iran, 55 accessions
were analyzed by SRAP markers. Twelve primer combin
ations produced 171
polymorphic bands. The cumulative dendrogram deline
ated fennel accessions into five
major groups in accordance to the geographical regi
ons 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 withi
n the populations. The studied
populations showed high genetic differentiation (Gs
t= 0.52) and low gene flow (Nm= 0.46).
Among the studied populations, Yazd and Kerman acco
unted 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 acc
essions. 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.
