In this research phylogenetic relationships of the two genera Fragaria and Duchesnea, including four species ( Fragaria viridis, F. vesca, Duchesnea indica and D. chrysantha) and 2 of their closely related species (Potentilla reptans and P. micrantha) plus 2 Fillipendulla species ( representing outgroups) were carried out using morphological traits. Primarily, morphological evidences of 30 taxa were carefully examined. Then, phylogenetic analysis was conducted in two steps, 1) using 38 quantitative and qualitative characters 2) using 10 selected evidences. For this, all studied morphological characters were coded and analyzed by Maximum parsimony method (MP). Data analysis was carried out through the heuristic search embedded in the PAUP software. The result emphasizes the separation of the two subtribe Potentillinae and Fragariinae. It also shows monophyly of Fragaria and Duchesnea. Furthermore, based on the current findings, Potentilla is a closest relative of Duchesnea. Among the studied morphological characters14 (9 from the first and 5 from second analysis) isolates Fragaria from Duchesnea; and 6 (4 from the first analysis and 2 from the second analysis) separates Duchesnea from Potentilla. However, intra-species relationships between the Fragaria species) except for 4 taxa) remained unresolved.

Abstract [Persian]

در این تحقیق روابط فیلوژنتیکی دو جنس Fragaria و Duchesnea، چهار گونه) Fragaria viridis، F. vesca، Duchesnea indica و D. chrysantha ) و 2 گونه خویشاوند نزدیک آنها (P. micrantha و Potentilla reptans ) و 2 گونه Fillipendulla ( به عنوان برون گروه)، با استفاده از صفات مورفولوژیکی مورد بررسی قرار گرفت. ابتدا صفات ریخت شناسی 30 تاکسون به دقت مورد ارزیابی قرار گرفت.سپس تحلیل فیلوژنتیک در دو مرحله 1) با استفاده از 38 صفت کمی و کیفی و سپس 10 صفت انتخابی انجام شد. برای این کار صفات ریخت شناسی کدگذاری شدند و داده ها را به روش بیشینه پارسییمون (MP) مورد تجزیه و تحلیل قرار گرفتند.تحلیل داده ها از طریق جستجوی ابتکاری تعبیه شده در نرم افزار PAUP انجام شد. نتیجه این تحقیق بر جدایی دو زیرطایفه Potentillinae و Fragariinae تأکید دارد. مچنین بیانگر تک نیا یی Fragaria و Duchesnea می باشد. بعلاوه بر اساس یافته های این بررسیPotentilla نزدیکترین خویشاوند Duchesnea می باشد. از میان صفات مورد مطالعه بررسی در مجموع 14 صفت ( شامل 9 صفت از تحلیل اول و 5 صفت از تجزیه دوم) موجب جداسازی Fragaria از Duchesnea و 6 صفت ( 4 صفت از اولین تحلیل و2 صفت از تجزیه دوم) سبب تفکیک Duchesnea از Potentilla شدند. با این حال، روابط درون گونه ایی دو گونه ی Fragaria ( به غیر از 4 تاکسون) حل نشده باقی ماند.
