摘要
中甜207(原代号D0296)是以2个二倍体多粒型有粉系DP14(P1)和DP03(P2)为亲本,按3∶1比例混合栽植自由授粉制种,配制而成的杂交组合,该品种2001～2003年参加全国甜菜品种区域试验和生产试验,平均根产量分别为41583.1kg/hm2和48938.5kg/hm2,与当地对照品种持平,平均含糖率为17.10%和17.90%,比当地对照品种提高1.27度和1.00度,平均产糖量为7147.7kg/hm2和8799.5kg/hm2,比当地对照品种提高9.9%和2.4%。该品种表现较抗褐斑病,耐根腐病。主要适宜在黑龙江的友谊、哈尔滨地区,吉林的长春、白城地区,内蒙古的兴安盟,甘肃黄羊镇,新疆的塔城、和静、昌吉等地区种植。
A new sugarbeet variety, Zhongtian 207 （original code： D0296）, comes from cross offspring of 2 polyembryony diploid lines, DP14 （P1） and DP03 （P2） by 3：1 under a natural condition. In both national sugarbeet variety regional experiment and demonstration experiment from 2001 to 2003, the mean root yield was respectively 41583.1 kg/ha and 48938.5 kg/ha, near the control variety, the sugar content was 17.10% and 17.90%, increased by 1.27°S and 1.00°S in comparison with the control variety, the sugar yield was 7147.7 kg/ha and 8799.5 kg/ha, increased by 9.9% and 2.4% in comparison with the control variety, respectively. The variety has shown a good resistance to leafspot and tolerance to root rot. It was suitable to plant in the both Youyi and Harbin areas of Heilongjiang province, Changchun and Baicheng areas of Jilin province, xing＇an league areas of Inner Mongolia, Huangyangzhen areas of Gansu province, and Tachen, Hejing and Changji areas of Xinjiang autonomous region.
