摘　　要：对11个多倍体甜菜品种骨干亲本的主要农艺性状进行了鉴定,发现它们在根产量、含糖率和产糖量方面差异极显著。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。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。Through identification of important traits of 11 main lines for sugarbeet polyploid varieties, there were significant different among the root yield, sugar content and sugar yield. 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. 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.
