Amplification of Ssr Markers: Eighty six SSR primers
were used for preliminary amplification of isolated DNA.
The amplification reactions were conducted following the
protocol proposed by Williams et al. [13] with a final
volume of 10 μl containing: 1.0 μl of DNA (10ng/μl); 1.0 μl
10x PCR buffer containing 15 mM MgCL2 (Promega), 0.8
μl of dNTPs (2.5 mM each), 0.2 μl of TaqDNA polymerase
(Promega; 5 u/μl), 2.0 μl of the forward and reverse
primer (1 μM each) and 5.0 μl of distilled water.
The amplifications of the primers were carried out in a
BIORAD-MyCycler-thermocycler with the following
amplification conditions: a denaturing step at 95°C for
3min.; followed by 40 cycles, each one consisting of
