摘　　要：针对西南山区特殊立体生态特点和山区玉米产区的主要问题,从品种的适应性、遗传基础、生态类型间的关系考虑,选育适宜西南山区的玉米杂交种。2000年在杂交种产量比较试验中。西山66比对照(交三单交)平均增产20％,在2001～2002年省区试和生产试验中,西山66比对照(兴黄单89-2)平均增产9.49％和26.4％。西山66杂交种表现抗逆性强、果穗大、结实性好、熟期适中、高产质优等特征,适宜在我国西南山区主要玉米产区种植。Xishan 66, a new maize hybrid variety, was bred for adapting the special ecological condition of southwest mountainous area in the light of thinking the relationship of maize hybrid suitability, genetic base and ecological type. The yields of Xishan 66 were 9. 49% and 26. 4% higher than CK (Xinghangdan 89-2) in the regional and production tests during 2001-2002 respectively. Xishan 66 possesses strong adversity resistibility, bigger fruit ear, middle mature period, higher seed setting rate, higher yield and good quality and has been approved by Guizhou Committee of Crops Variety Examination in 2003.
