| 摘 要： | 马铃薯脱毒种薯生产和利用是马铃薯生产的重要环节,传统的脱毒种薯生产体系因繁殖周期长,病毒再侵染风险高,使种薯质量很难保证。本研究以品种脱毒和试管薯生产为基础,以微型薯生产和标准种薯生产为扩繁环节,建成了二年制种薯生产体系。该体系将种薯生产在田间多年繁殖改进为只需一年繁殖,从而降低了病毒再侵染机率,保证了脱毒种薯质量。

| Abstract: | It is the main measure of potato production quality of seed tubers is difficult to guarantee with existed seed high crises of virus reinfection. The present research, based to produce and use virus-free seed tubers. The potato system since its long propagation cycle and on virus elimination and microtuber production, established the two-year seed potato system including propagations of minitubers in net-house and standard seeds in the field. The two-year system requiring seed tuber production for only one year in the open field, rather than several years necessary for the conventional method, ensures reduction of virus infection and hence the improvement of seed tuber quality. |
