摘　　要：甜菜新品种内甜抗203(原名内102)是多胚型二倍体抗丛根病品种。该品种在内蒙古自治区甜菜品种抗病区域试验中,平均根产量44715.0kg/hm2,比对照种甜研303提高97.7%;含糖率15.67%,比对照种提高1.34度;产糖量7006.8kg/hm2,比对照种提高116.2%,丛根病病情指数17,比对照种降低18。在内蒙古自治区甜菜品种普通组生产试验中,根产量69225.0kg/hm2,比对照提高62.0%;含糖率16.85%,比对照提高0.08度;产糖量11664.4kg/hm2,比对照提高62.8%,达到丰产型品种标准;在内蒙古自治区甜菜品种抗病组生产试验中,根产量、含糖率、产糖量分别比对照提高182.6%、1.10度、203.8%,丛根病病情指数比对照降低47.9,达抗丛根病型品种标准。Neitiankang 203 is a multigerm diploid sugarbeet hybrid with rhizomania resistance. In the test of sugarbeet disease-resistance variety in the Inner Mongolia, the average root yield, sugar content and sugar yield of the variety were 44715.0kg/ha, 15.67% and 7006.8kg/ha, which increased by 97.7%, 1.34°S and 116.2% in comparison with Tianyan 303, respectively, and the rhizomania-disease index was 17, decreased 18 in comparison with the control variety. The general demonstration experiment in the Inner Mongolia, the root yield, sugar content and sugar yield were 69225.0kg/ha, 16.85% and 11664.4kg/ha, increased by 62.0%, 0.08°S and 62.8% respectively, in comparison with the control variety, the disease-resistance demonstration experiment, the root yield, sugar content and sugar yield increased by 182.6%, 1.10°S and 203.8%, respectively, rhizomaniadisease index decreased by 47.9 in comparison with the control variety. Therefore, this variety reached high yield and rhizomania resistance level.
