甜单301为中国农业科学院甜菜研究所育成的甜菜遗传单粒型多倍体杂交种,在1999～2001年的黑龙江省甜菜品种区域试验和生产试验中,原料根平均产量为39791.9～40868.2kg/hm2,比对照种甜研303提高13.74%～17.05%;平均含糖率为16.45～17.16度,与对照种甜研303比提高-0.77～0.35度;原料根产糖量为6545.8～7013.0kg/hm2,比对照种甜研303提高10.9%～16.42%。甜单301的上述经济指标亦优于目前主栽的甜单二号。甜单301单粒率高、发芽势强、适应性广,适与甜菜育苗移栽和机械化精量点播等集约化栽培技术配套使用,原料生产的保苗密度(收获株数)以72000～78000株/hm2为宜。甜单301适宜在黑龙江省的友谊、讷河、海伦、宁安和依安等甜菜产区推广种植。
Sweet single 301 is a sugarbeet genetic single-grain polyploid hybrids bred by the Institute of Beet Research, Chinese Academy of Agricultural Sciences. During the regional trials and production tests of sugar beet varieties in Heilongjiang Province from 1999 to 2001, the average yield of raw material roots was 39,791.9 to 40,868.2 kg / hm2, increased 13.74% ~ 17.05% compared with sweet wheat 303; the average sugar content was 16.45 ~ 17.16 degrees, increased -0.77 ~ 0.35 degrees compared with sweet corn 303; the sugar content of raw material root was 6545.8 ~ 7013.0 kg / hm2, which is 10.9% ~ 16.42% higher than the control sweet study 303. The sweetness of the above 301 economic indicators is also better than the current main sweet twins. Sweet single 301 single grain rate, strong germination, wide adaptability, suitable for sugar beet seedling transplanting and mechanized precision on-demand and other intensive cultivation techniques supporting the use of raw material production seedling density (harvested) to 72000 ~ 78000 plants / hm2 is appropriate. Sweet single 301 is suitable for planting in the beet producing areas of Heilongjiang Province Friendship, Nehe, Helen, Ning’an and Yi’an.
