摘　　要：甜菜新品种‘HDTY04’是以新型细胞质二倍体单胚雄性不育系‘MDms4-3’为母本,以‘DP30’多胚二倍体授粉系为父本杂交选育而成。该品种于2014—2015年黑龙江省甜菜品种区域试验鉴定中,平均根产量为59930.1 kg/hm^(2),比对照品种增产15.3%,平均含糖率为18.40%,比对照品种提高1.20个百分点,平均产糖量为10989.6 kg/hm^(2),比对照品种提高24.3%。该品种表现抗褐斑病,耐根腐病和丛根病,产量性状、质量性状表现稳定优异,适宜在黑龙江省的哈尔滨、齐齐哈尔、嫩江、红兴隆等甜菜产区春季种植。A new sugar beet cultivar HDTY04 was developed by crossing a new monogerm diploid male sterile sugar beet line MDms4-3 as male parent and a multigerm diploid pollinating line DP30 as female parent.According to the regional sugar beet test results in Heilongjiang from 2014 to 2015,the average root yield of HDTY04 was 59930.1 kg/hm^(2),15.3%higher than the control cultivar;the average sugar content was 18.40%,1.20 percentage point higher than the control cultivar;and the average sugar yield was 10989.6 kg/hm^(2),24.3%higher than the control cultivar.Moreover,HDTY04 was verified to be resistant to leaf spot,and tolerant to root rot and rhizomania disease.This cultivar is suitable for growing in Harbin,Qiqihar,Nenjiang,Hongxinglong areas in Heilongjiang.
