ATTENUATED VIRUS OF FEATHERY MOTTLE VIRUS OF SWEET POTATO, METHOD FOR CONTROLLING ZONAL INTERNAL BARK NECROSIS OF SWEET POTATO USING ATTENUATED VIRUS AND SWEET POTATO HAVING RESISTANCE TO STRONGLY POISONOUS STRAIN OF FEATHERY MOTTLE VIRUS OF SWEET POTATO

摘要

PROBLEM TO BE SOLVED: To provide an attenuated virus having control effect on zonal internal bark necrosis of sweet potato and to provide a control technique utilizing the attenuated virus.;SOLUTION: The control technique has extremely slight virus symptom against root tuber of sweet potato and selects/isolates the attenuated virus capable of preventing occurrence of zonal internal bark necrosis of sweet potato by vaccinating the attenuated virus to a virus-free seedlings form the natural world and utilizes the attenuated virus.;COPYRIGHT: (C)2004,JPO&NCIPI
