The objectives of the present study is to analyze the
genetic diversity among 15 different cultivars of date palm at the experimental
farm of Qatar University using Simple Sequence Repeat (SSR) markers and
find out the genetic similarity and/or diversity among the well known
Qatari date palm cultivars. DNAs were extracted from the young fresh leaves.
Among 16 primer pairs tested for their ability to generate expected SSR
banding patterns in Qatari date-palm genotypes, 10 primers successfully
produced clear single bands in most of the studied genotypes. So, far,
six SSR primers did not amplify clear bands in our genetic materials even
using different PCR conditions. The amplified SSR band sizes ranged from
100-300 bp. A total of 40 alleles with an average of 4 alleles per locus
were scored. Similarity coefficient matrix was computed to cluster the
data and to draw precise relationships among the fifteen studied Qatari
date palm genotypes.
