摘要
中国拥有十分丰富的烟草种质资源。利用烟草病毒病抗性种质培育广谱抗性品种,是防治烟草病毒病危害的有效手段。阐述了中国烟草病毒病抗性种质资源的鉴定现状,从物理化学诱变、细胞工程、转基因技术等3个方面介绍了烟草病毒病抗性种质创新的进展。最后,从当前存在的问题及未来发展方向,对烟草病毒病抗性种质资源的鉴定与创新进行了展望。
China has very abundant tobacco germplasm resources. Using tobacco virus diseases resistant germplasm resources to breed new varieties with broad-spectrum resistance is an effective way to control the damages of tobacco virus diseases. At first, the paper described the identification situations of tobacco virus diseases resistant germplasm resources iu China. Then, the innovation advances of tobacco virus diseases resistant germplasm resources were introduced fl'om three aspects, which including physical and chemistry mutagenesis, plant cell engineering, and transgenic technology. Finally, according to the problems existed at present and the developmental direction in the future, we discussed the prospect of identification and innovation of tobacco virus diseases resistant germplasm resources.
