摘　　要：本文研究的48个亚洲棉(G.arboreum L.)品种,分别属于六个地理族系(GeographicalRaces),用8个质量性状进行形态分类,获得32个类型。其中苏丹棉4类,印度棉7类,缅甸棉2类,垂铃棉2类,孟加拉棉9类,中国棉8类。This paper presented the observation and taxonomy of 48 varieties in G. arboreumL. introduced recently from foreign countries. The experiment was conducted in1988--1990 in Nanjing, and 27 main triats of G. arboreum L. were studied.Thirty- two types were classified according to 8 qualitative characters i.e. stem color (SC),leaf shape (LS), leaf nectary (LN),nectary in bract (BN), corolla color (CC), petalspot color (PSC), lint color (LC), and fuzz (Fu) or naked (Na) seed, whichwere utilized as the basis for classification. Among these 32 types, 4 were divided intoG. arboreum race soudanense, 7 into G. arboreum race indicum, 2 into G. arboreumrace burmanicum, 9 into G. arboreum race bengaledense, 2 into G. arboreum.cernuumand 8 types into G. arboreum race sinense. Furthermore, the variety bur--1 andbur--2 of G. arboeum race burmanicum having a close relationship with G.arborean race soudanense and G. arboreum race cernuum respectively, were observed.
