Karyological Studies on the Solanaceae

Awatif I. El-Nahas, Sayed. F. Khalifa and Maged. M. Abou-El-Enain

Comparative karyological studies for 23 taxa of the Solanaceae have been presented and their taxonomic aspects are discussed. It was concluded that the origin of the family is a taxon with basic chronomosome number of x = 7 or 8 which gave rise to other taxa by aneuplodiy and polyploidy. Nictiana elate and Browallia viscose are found to be less evolved than the other species studied. Concerning the total form percentage (TF%) a reverse trend towards increasing the degree of karyotype symmetry with advancing evolution is concluded.
