戴菊的幾個亞種已被描述。[23] 在歐亞大陸,一般公認有九個非常相似的亞種,牠們之間的差異僅在於羽毛色調的細節。[8] 在基因層面,兩個中亞型態,R. r. sikkimensis 和 R. r. himalayensis 彼此非常接近,僅在近期才有所分化,但牠們與西部亞種約在280萬年前分化。[22]
R. r. himalayensis(波拿巴,1856):分佈於喜馬拉雅山脈;與指名亞種相似,但上半身顏色略淡,且下半身更白。
戴菊东北亚种R. r. japonensis(布萊基斯頓,1862):分佈於東亞,包括日本、韓國、中國和西伯利亞;牠比指名亞種更綠,上半身顏色更深,且有寬闊的白色翼斑。在中国大陆,分布于东北、河北、河南、西至甘肃和青海、山东、江苏、浙江、福建等地。该物种的模式产地在日本。[24]
戴菊新疆亚种R. r. tristis(Pleske,1892):分佈於中國和中亞,冬季遷徙至阿富汗東北部。理察·梅納茨哈根記錄的來自拉達克的這種種群被認為是偽造的。[25] 這亞種具有明顯的特徵,冠羽黑邊幾乎缺失。雄鳥的頭頂比其他型態更黃,且下半身顏色更加暗淡偏灰。在中国大陆,分布于新疆.青海等地。该物种的模式产地在Turkestan。[26]
R. r. coatsi(Sushkin,1904):分佈於俄羅斯和中亞,上半身顏色比指名亞種更淡。
戴菊西南亚种R. r. yunnanensis(Rippon,1906):分佈於東喜馬拉雅山脈、緬甸和中國;牠類似R. r. sikkimensis,但整體顏色更深,上半身為深綠色,下半身顏色較深的黃褐色。在中国大陆,分布于甘肃、陕西、四川、贵州、云南、西藏等地。该物种的模式产地在云南。[27]
R. r. hyrcanus(扎魯德尼,1910):僅分佈於伊朗;與R. r. buturlini相似,但顏色稍深。
R. r. buturlini(Loudon,1911):分佈於東歐、高加索和中亞。上半身顏色比指名亞種更淡,呈灰綠色而非橄欖色。
戴菊青藏亚种R. r. sikkimensis(R. 邁納茲哈根 和A. 邁納茲哈根,1926):分佈於印度和中國。牠比R. r. himalayensis顏色更深,比指名亞種更綠。在中国大陆,分布于青海、甘肃、西藏等地。该物种的模式产地在锡金。[28]
來自加那利群島的鳥類特別具有區別性,牠們有黑色的前額,粉紅褐色的下半身和顏色更深的閉合翅膀,[4] 以前有時被視為火冠戴菊的亞種或不同的Regulus物種。[30] 不論牠們棲息在哪個島嶼,牠們都曾被稱為「特內里費戴菊」;然而,2006年的一項關於這些鳥類鳴聲的研究表明,牠們實際上由兩個可以在聲音上區分的戴菊亞種組成:R. r. teneriffae 出現在特內里費,而新描述的亞種R. r. ellenthalerae,西加那利群島戴菊,則出現在拉帕爾馬島和耶羅島的小島上。[31]
特內里費戴菊R. r. teneriffae(塞博姆,1883):分佈於特內里費島和拉戈梅拉島,加那利群島;這是一個具有區別性的小亞種,前額為黑色,下半身為粉紅褐色。
西加那利群島戴菊R. r. ellenthalerae(Päckert et al.,2006):分佈於拉帕爾馬島和耶羅島,加那利群島。
