| Abstract: | Sugarbeet Rhizomania tolerant line NC-8 was developed by Sugarbeet line selection. It is N-type, multigerm, diploid variety, has higher tolerance to Rhizomania, The average root yield in Gansu Hexi region with Rhizomania infected has reached 53.31t /ha, average sugar yield reached 8058 kg/ha, high than CK(Gantang-1)248.4% and 382.1% respectively. Average sugar content was 15.0%, increased 3.49 percentage points than CK. Not only in Rhizomania infected field but also in ordinary field it can be planted. |
