在甜菜生产中,甜菜的茎、叶和块根受多种病毒、真菌侵染,可导致产量、品质下降。目前,多数病害缺乏有效、经济的防治手段,有些病害防治的化学药剂具生物和环境毒害,有些药剂易于产生病原抗药性。因此抗病育种成为最重要的病害防治手段。抗病品种可以减少病害导致的产质量损失, In beet production, beet stems, leaves and roots are infected by many viruses and fungi, which can lead to the decrease of yield and quality. At present, most diseases lack effective and economical means of prevention and treatment. Some chemical agents for disease prevention and treatment are biologically and environmentally toxic and some drugs are susceptible to pathogenic drug resistance. Therefore, disease-resistant breeding has become the most important disease control measures. Disease-resistant varieties can reduce the disease caused by the loss of quality and quantity,
