Taxonomic Revision on Genus Brassica L. (Cruciferae A. Juss.) in Egypt

Abstract

This study includes taxonomic revision, documentation, description and distribution of 8 Brassica species in Egypt; Brassica cretica Lam., Brassica juncea (L.) Czern., Brassica napus L., Brassica nigra (L.) K. Koch., Brassica oleracea L., Brassica rapa L., Brassica tournefortii Gouan. and Brassica deserti Danin & Hedge. Fresh specimens were collected from El- Qaluobea and El-Fayoum
governorates, Egypt. Herbarium specimens were examined, photographed and kept in Flora and Phytotaxonomy Research Department to be available for the taxonomic researchers for further study. The results of this study showed the importance of morphological traits for taxonomic evaluation among the studied taxa of genus Brassica in Egypt. Moreover, a constructed key to Brassica taxa was designed.
