马铃薯黑胫病抗性品种的筛选与评价
Screening and Evaluation of Potato Varieties with Blackleg Resistance
摘要
Abstract
In order to solve the problem of lack of resistance breeding resources in the control of potato blackleg disease in China,a research was conducted by inoculation on hole tuber in vitro and by acupuncture inoculation method in vivo under greenhouse condition.Twenty-four potato varieties from Maine State of US were tested for the resistance to pathogenic bacteria Pectobacterium wasabiae WPP163 and Dickeya dianthicola ME30.The results showed that after inoculated by WPP163 in vitro,the varieties showing resistance included Sangre,Norglean,Ranger Russet and Red Burt,accounting for 16.67％ of the tested varieties.After inoculated by ME30 in vitro,Ranger Russet showed high resistance,and accounted for 4.17％ of the tested varieties.The varieties presenting resistance included Wasca,Satapa,Pantonac,and Sangre,accounting for 16.67％ of the whole tested varieties.In greenhouse experiment,after inoculated by WPP163,the varieties presenting resistance included Ranger Russet,Sangre,and Norglean,the varieties presenting moderate resistance included Wasca,Pantonac,Red Burt,Satapa,Reba,White Cloud,and Red Warba,while others were moderately susceptible and susceptible.After inoculated by ME30,the variety showing high resistance was Ranger Russet,the varieties showing resistance included Wasca,Satapa,and Sangre,the varieties showing moderate resistance included Pantonac,Red Warba,Sebago,Norcheif,and Rural New Yorker,while others were moderately susceptible and susceptible.Ranger Russet and Sangre,which had good resistance to the two pathogens both in vitro and in vivo under greenhouse condition,were selected in this experiment.It provided a scientific basis for the safety production of potato and introduction of resistance varieties to blackleg in China.关键词
