摘　　要：黔单12号是以106为母本与138配组选育而成的高产优质多抗杂交玉米新品种.2002年通过贵州省农作物品种审定委员会审定.2000～2001年贵州省区试平均产量604.2 kg/667m2,比对照增产23.7%;2002年全国21省(区)、市25个点的国家预备试验中,平均产量615.1 kg/667m2,比对照平均增产3.4%;全生育期在贵州平均为126 d,西北地区平均为134 d,东北和华北地区平均为130 d,黄淮海地区平均为101 d.抗大、小斑病和茎腐病,中抗矮花叶病,高抗纹枯病和玉米螟,感丝黑穗病.抗倒伏、抗旱或耐旱性强.适宜在北纬35°以下地区推广种植,西南玉米区特别是云贵高原更为适宜.The new hybrid maize Qiandan 12 is combined from the female line 106 and male line 138. It had been approved by Guizhou Committee of the Crops Varieties Examination in 2002. The average yield was 9 603 kg/ha, increased 23.7% than CK (during) 2000 to 2001 in regional test of Guizhou and 9 226.51 kg/ha, increased 3.4% than CK in 25 sites of 21 provinces for the (national) preparing examination. The growth period of Qiandan 12 varies in different regions, 126 days in Guizhou, 134 days in northwest, and 130 days in northeast and north of China, and 101 days in Hung Huaihai areas in average. This hybrid resists maize leaf blight, maize leaf spot, and stalk rot, meddle-resistant to rough dwarf, high-resistant to sheath blight and corn borer, it can be infected by head smut. It is resistant to lodging, drought, or drought enduring. It can be implemented in the areas below north (latitude) 35°, (especially) the areas of Yungui Plateau of China.
