- The cercospora leaf spot is one of the main diseases infecting sugarbeet. 褐斑病是甜菜的主要病害之一,危害性很大。
- The genetic correlation indicated that root yield,sugar content and sugar yield showed positive relations except Cercospora leaf spot resistance. 遗传单粒型多倍体品种的各项经济性状指标相对较差。 遗传相关性分析表明,除褐斑病级与根产量、含糖率及产糖量呈负相关外,其余3个性状间呈现正相关关系。
- But they were not resistant to cercospora leaf spot of sugarbeet and produced a lower sugar content in normal or light rhizomania infected field. 但该类品种在无丛根病或轻度感染丛根病地种植,均表现不抗褐斑病,含糖分较低。
- The root yield and sugar content of tetraploid lines were higher than that of diploid lines.However, the Cercospora leaf spot resistance had no significant differences. 四倍体品系的根产量和含糖率均优于二倍体材料，而褐斑病抗性差别不大。
- The analysis of genetic correlation indicated that there was a positive relation among the root yield, sugar content and sugar yield except Cercospora leaf spot resistance. 遗传相关性分析表明,除褐斑病病情与根产量、含糖率及产糖量呈负相关外,其余3个性状间均呈正相关。
- Abstract : It is of great important to study the cercospora leaf spot resistance of sugar beet M14 which has No. 9 chromosome of Beta corolliflora Zoss in addition. 摘要 ： 甜菜M14品系由于附加了一条野生白花甜菜第9号染色体，因此，研究其是否具有抗病性以及抗病程度的强弱具有十分重要的意义。
