【摘要】 内糖(ND)38是二倍体单粒雄性不育杂交种。母本是来自德国KWS公司的CMS66181,父本是采用胚珠培养和常规育种技术结合多代选育而成的优良品系9-7705。1999～2000年参加内蒙古自治区抗(耐)丛根病甜菜品种区域试验,平均根产量、含糖率、产糖量分别比对照甜研303提高85.5%、1.31度和101.2%,病情指数比对照低11.6。2001年在中度(3级)丛根病地进行了生产示范试验,根产量、含糖率、产糖量分别比对照提高127.5%、1.68度和154.7%,病情指数降低33.0。在华北、西北甜菜平作区适宜种植密度为7.5～8.25万株/hm2。更多还原

【Abstract】 The variety of sugarbeet Neitang (ND)38is a hybrid of monogerm CMS diploid,it is hybridized from the female parent (CMS66181A,from KWS)with diploid pollinator9-7005bred by ovule culture and conventional breeding,the sterile rate of CMS is stabilized at more than98%.The regional Rhizomania resistant sugar beet variety test was performed in the Inner-Mongolia in1999～2000,the results showed that root yield,sugar content and sugar yield increased by85.5%,1.31°S and101.2%respectively,and disease index decreased by11.6to comparing with CK (Tianyan303);its productive demonstration experiment was conducted in the field of medium Rhizomania access in2001,the root yield,sugar content and sugar yield increased by127.5%,1.68°S and154.7%respectively,and disease index decreased by33.0in comparison with CK (Tianyan303).Its suitable density is about 75000～82500plants per ha in the north China and the northwest China.更多还原
