This study evaluates the taxonomic composition and morphological diagnostic characters of Silene L. in the Fergana Valley. Based on literature, herbarium material, regional floras, and taxonomic sources, 32 species were assigned to 12 sections. Sect. Sclerocalycinae was the most species-rich section with eight species (25.00%), followed by sect. Holopetalae with six species (18.75%). The principal characters used to distinguish sections were calyx shape and venation, degree of calyx inflation, division of the petal limb, structure of the petal claw, anthophore pubescence, inflorescence type, and selected vegetative traits. The results provide a concise taxonomic framework for identification of Silene species in the Fergana Valley and a basis for subsequent ecological, biogeographical, and conservation studies.

В исследовании оценены таксономический состав и морфологические диагностические признаки рода Silene L. в Ферганской долине. На основе литературы, гербарных материалов, региональных флор и таксономических источников 32 вида отнесены к 12 секциям. Наиболее богатой видами оказалась секция Sclerocalycinae (восемь видов; 25,00%), за ней следует секция Holopetalae (шесть видов; 18,75%). Основными признаками для разграничения секций служили форма и жилкование чашечки, степень её вздутости, рассечённость пластинки лепестка, строение ноготка лепестка, опушённость антофора, тип соцветия и отдельные вегетативные признаки. Результаты дают компактную таксономическую основу для определения видов Silene в Ферганской долине и базу для последующих экологических, биогеографических и природоохранных исследований.

Ushbu tadqiqotda Farg‘ona vodiysidagi Silene L. turkumining taksonomik tarkibi va morfologik diagnostik belgilari baholandi. Adabiyotlar, gerbariy materiallari, mintaqaviy floralar va taksonomik manbalar asosida 32 tur 12 seksiyaga ajratildi. Turlarga eng boy seksiya — sect. Sclerocalycinae (sakkiz tur; 25,00%), undan keyin sect. Holopetalae (olti tur; 18,75%). Seksiyalarni farqlashda asosiy belgilar sifatida kosachaning shakli va tomirlanishi, kosachaning shishganlik darajasi, gultoji plastinkasining bo‘linishi, gultoji tirnoqchasining tuzilishi, antoforning tukliligi, to‘pgul turi hamda ayrim vegetativ belgilar xizmat qildi. Natijalar Farg‘ona vodiysida Silene turlarini aniqlash uchun ixcham taksonomik asos beradi va keyingi ekologik, biogeografik hamda muhofaza tadqiqotlari uchun zamin yaratadi.
