摘要： 利用棉花远缘杂交技术，用海岛棉（G.barbadense）、野生瑟伯氏棉(G.thurberi)、陆地棉(G.hirsutum)进行杂交，对杂交铃喷(滴)GA3(50ppm)、NAA（40ppm）、杂种胚离体培养，试管内染色体加倍，对获得的种间杂种进行回交较育，南繁北育，异地鉴定选育而成棉花新品种“石远321”。1993~1994年国家黄河流域棉花品种区域试验，亩产子棉、皮棉、霜前皮棉均居八个参试品种第一位，其中霜前皮棉产量885 kg/hm2，比对照增产19.7%，是1982~2000年19年间国家黄河流域棉花品种区域试验中霜前皮棉增产幅度最大的一个品种。

Abstract: Using G.barbadense G.thurberi and G. hirsutum crossing through distant hybridization of cotton, By dropping GA3(50ppm) and NAA(40ppm) on the pollinated flower,hybrid embryo culture,and in Vitro Colchicine treatment ,backcrossing to the hybrid , through continual selecting and breeding ,cultivate cotton new variety ShiYuan 321. It’s seed yield and lint yield and prefrose lint yield is the first of all the test varieties in the cotton regional test for the Yellow River Valley in 1993-1994. Its mean prefrost lint yield were 885kg.hm-2,19.7% higher than those of control “Zhongmiansuo”12 respectively ,it is the largest variety of prefrost lint yield than the control in the cotton regional test for the Yellow River Valley between 1982~2000.
