摘要
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。
Tiandan301bred by Sugarbeet Research Institute of CAAS.It tested in the Heilongjiang Regional Tests and Demonstrations in1999~2001,the results shown that the root yield39791.9~40868.2kg/ha,the yield increased13.74%~17.05%than CK Tianyan303;Sugar content 16.45%~17.16%and lower-0.77%~0.35%than CK Tianyan303;Sugar yield6545.8~7013.0kg/ha higher10.9%~16.42%than CK Tianyan303,Tiandan301is better than Tiandan2.Tiandan301has higher monogerminity and high germinative energy,and with wide adaptive faculty.It can use to seedling transplanting and with machinery precision drill,the population with72000~78000plants /ha.This variety can recommand to plant in Youyi,Nehe,Hailun,Ningan and Yian growing areas.
