التوصيف الجزيئي لعشبة الباذنجان البري .Solanum elaeagnifolium Cav في سورية

الملخص EN

Silverleaf nightshade (Solanum elaeagnifolium Cav.) is the most serious invasive weed, threatening crops in Syria.

Molecular Characterization of the two genotypes of silverleaf nightshade (violet and white flowers) spread in the Syrian environment was done using ISSR-PCR technique.

The ISSR-PCR technique has showed polymorphism (91.33%) between silverleaf nightshade and cultivated eggplant, as the wild and cultivated species were separated in two different clusters.

The first cluster included both violet and white flowers genotypes of silverleaf nightshade, and had two groups: the first group included the genotype with violet flowers, collected from two different geographical sites, and they were at a high genetic relevance degree with a genetic distance of about 10.48, while, the second group included the genotype with white flowers, with a genetic distance of about 20.62.

This raises the possibility of renaming it as a new species or variety of silverleaf nightshade.

The second cluster included cultivated eggplant varieties
