摘要
甜研311(原代号HTP02)是以多粒四倍体品系TP-3为母本,父本为4个多粒二倍体品系(DP08、DP02、DP03和DP04),4个父本品系以2∶1∶1∶1的比例混合授粉,父母本按1∶3比例栽植配制而成。该品种于2005～2008年通过了黑龙江省甜菜品种区域试验和生产试验,平均根产量分别为39576.2kg/hm2和47501.7kg/hm2,分别比统一对照品种增产11.9%和21.7%;平均含糖率为16.8%和17.4%,比统一对照品种提高0.5度和1.0度;平均产糖量为6725.4kg/hm2和8348.9kg/hm2,比统一对照品种提高15.9%和30.4%。该品种表现较抗褐斑病,耐根腐病。主要适宜在黑龙江的牡丹江、齐齐哈尔、大庆、哈尔滨等地区种植。
New sugarbeet variety,Tianyan 311（original code： HTP02）,was crossed from a polyembryony tetraploid line TP-3 as the female parent with 4 polyembryony diploid lines（DP08,DP02,DP03 and DP04 crossing by 2：1：1：1） as the male parent through natural pollination as 3：1.In both Heilongjiang sugarbeet variety regional experiment and demonstration experiment during the years of 2005 to 2008,the mean root yield was 39576.2 kg/ha and 47501.7 kg/ha,increased by 11.9% and 21.7%,the sugar content was 16.8% and 17.4%,increased by 0.5°S and 1.0°S,the sugar yield was 6725.4 kg/ha and 8348.9 kg/ha,increased by 15.9% and 30.4% in comparison with the control variety,respectively.The new variety has shown a good resistance to leafspot and tolerance to root rot.It was suitable to plant in the Mudanjiang,Qiqihaer,Daqing and Harbin areas of the Heilongjiang province.
