Morphological characterization and chromosomal number of some local genotypes of tulip (Tulipaspp.) in Lattakia


Abstract in English

The aimsof this research were to morphologically characterize 27 local genotypes of tulip,to evaluate the genetic variability between them using 32 morphological traits, and to determine their chromosomal number. The results allowed the distinction between the studied genotypes based on the morphological characterization of all vegetative,floral andbulb traits. Results confirmed that the main limiting factor for distribution over the screened regionwas the high above sea level.All genotypes were divided into two main groups, the firstone included genotypes located at 400 - 850 m of altitude, and the second one located between 950 -1450 m. The microscopic analysis results showed that all the studied genotypes were diploid (2n=2x=24 chromosomes). Depending on the results of the morphological characterization and the chromosomal number of local genotypes studied, it can be considered the closest to the specie Tulipaagenensis D.C.
