Abstract

The taxonomic status of the genus Sorghum Moench in Iran was evaluated. 163 accessions were studied using 75 morphological characters. The results indicated that the genus occurs in Iran with 4 species, S. propinquum, S. halepense, S.× drummondii, and S. bicolor. Sorghum propinquum (Kunth) Hitchc. is reported for the first time from Iran. This species is morphologically similar to S. halepense (L.) Pers. but differs from it in characteristics of rhizomes, leaf mid-vein, and inflorescence. Also, images and identification key for taxa is presented.

Abstract [Persian]

وضعیت طبقه‌بندی جنس Sorghum Moench در ایران ارزیابی گردید. تعداد ۱۶۳ فرد با استفاده از ۷۵ صفت ریخت‌شناختی مورد مطالعه قرار گرفتند. نتایج بیانگر حضور جنس سورگوم در ایران با ۴ گونه: S. propinquum، S. halepense، S.× drummondii و S. bicolor است. گونهS. propinquum (Kunth) Hitchc.  برای اولین بار از ایران گزارش می‌شود. این گونه از نظر ریخت‌شناختی مشابه گونه S. halepense بوده اما از نظر خصوصیات ریزوم، ویژگی‌های رگبرگ میانی و خصوصیات گل‌آذین تفکیک می‌شود. هم چنین کلید شناسایی و تصاویر آرایه‌ها ارائه می‌شود.
