摘　　要：中双六号具早熟、优质、高产、抗病性强、适应性广、含油量高等特点。在湖北省区试中平均产量2 613.75kg/hm^2,比对照中油 821增产6.75％;在全国区域试验中平均产量 1 894.95kg/hm^2,比对照中油 821增产17.33％。熟期比对照中油821早3d;含油量42.5％。2000年通过湖北省品种审定委员会审定。Zhongshuang No. 6, a new semi -- winter Brassica napus cultivar with early -- maturity, double -- low quality, higher -- yield and resistance to Sclerotinia sclerotiorum, was bred by multiple crossing and selection tech- nique. In the Regional Trial of Hubei Province from 1998 to 2000, Zhongshuang No. 6 get yield of 2 613. 75kg /hm^2 averagely, which outyielded the control cultivar Zhongyou 821 by 6. 75%. In the National Trial during 2001--2002, the cultivar showed yield of 1 894. 95kg/hm^2, which outyielded the control Zhongyou 821 by 17.33%. The Eruciac acid, glucosiolate and the oil content of Zhongshuang No. 6 were 0. 26%, 19. 21μmol/g, and 40. 4%, respectively. It was registered and released by Hubei Crop Variety Aproval Committee in 2000.
