摘要
内甜抗202(原名内101)是多胚型二倍体抗丛根病杂交种,父母本按1∶3比例自然杂交而成。该品种在内蒙古自治区甜菜品种抗病区域试验中,平均块根产量40954.5kg/hm2,比对照品种甜研303提高81.07%;含糖率16.38%,比对照品种提高2.05度;产糖量6729kg/hm2,比对照品种提高109.4%,丛根病病情指数0.13,比对照品种降低0.22。在内蒙古自治区甜菜品种普通组生产试验中,块根产量和产糖量分别比对照提高48.71%和47.81%,含糖率比对照降低0.10度;该品种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,块根产量、含糖率、产糖量分别比对照提高156%、1.39度、181.25%,丛根病病情指数比对照降低0.48,达到丰产、抗丛根病型品种标准。
Neitiankang 202 is a muhigerm diploid sugarbeet hybrid variety. Female parent and male parent was crossed through natural pollination by 3:1.In inner mongolia sugarbeet variety test from 2002 to 2003.the mean root yield was 40954.50kg/hm^2,increased by 81.07% in comparison with control variety;the mean sugar content was 16.38%,increased by 2.05°S;the mean sugar yield was 6729.00kg/hm^2,increased by 109.40%;the rhizomania rate was 0.13 grade,lowered by 0.22.1n inner mongolia sugarbeet variety demonstration test ofcommon group,the mean root yield and sugar yield increased by 48.71% and 47.81%,the mean sugar content lowered by 0.1°S.the variety has shown the high yield.In inner mongolia sugarbeet variety demonstration test of resistance group, the mean root yield, sugar content and sugar yield increased by 156% ,1.39°S and 181.25%.the rhizomania rate lowered by 0.48.the variety has shown a high yield and resistance to rhizomania and leafspot.
