甜菜新品种新甜18号的选育

Breeding of New Sugarbeet Variety Xintian 18

新甜18号是石河子甜菜研究所选育的抗丛根病二倍体雄性不育多粒型杂交种,在2006～2007年新疆维吾尔自治区甜菜品种区域试验中,两年14个点次的块根产量平均为82156.5kg/hm2,比对照KWS2409增产3.99%,含糖率平均15.21%,比对照低0.09度,产糖量平均12745.5kg/hm2,比对照增糖4.3%。在丛根病抗性鉴定中,两年平均块根产量为102182.3kg/hm2,比对照KWS2409增产33.92%,含糖率15.10%,比对照低0.08度,产糖量平均18475.5kg/hm2,较对照增糖35.0%。该品种丰产性能稳定,抗病性强,适应范围广。

Xintian 18 was a male sterile muhigerm diploid variety with resistance to sugarbeet Rhizomania. Data came from 14 sites in the Xinjiang sugarbeet variety experiment from 2006 to 2007, the mean root yield was 82156.5 kg/ha, increased by 3.99% in comparison with the control variety, KWS2409. The mean sugar content was 15.21%, decreased by 0.09°S in comparison with the same control variety. The mean sugar yield was 12745.5 kg/ha, increased by 4.3% in comparison with the control variety. In resistant Rhizomania experiment for two years, the mean root yield was 102182.3 kg/ha, increased by 33.92%; the mean sugar content was 15.10%, decreased by 0.08°S in comparison with the control variety; the mean sugar yield was 18475.5 kg/ha, increased by 35.0% in comparison with KWS2409. The variety has shown a high root yield and disease resistance as well as extensive adaptability.
