摘要
为进一步明确现有马铃薯品种资源材料的黑胫病抗性,从常用马铃薯育种亲本块茎材料中随机抽取40份,采用人工接种的方式对黑胫病抗性进行接种鉴定。结果表明:共鉴定出高抗材料1份,抗病材料8份,中抗材料13份,中感和感病材料18份。分别占供试材料的2.5%、20%、32.5%、45%。为今后进行马铃薯生产和开展抗黑胫病育种提供有价值的参考依据。
40 materials were taken from the potato parental tuber materials in a random for further clarifying existing potato variety resource materials with resistance to black leg,the resistance to black leg（Phytophthora nicotianae） was identified by artificial inoculation method.The results showed that 1 material with high resistance,8 materials with resistance,13 materials with medium resistance,18 materials with medium susceptibility and susceptibility,they accounted for 2.5%,20%,32.5% and 45% in experimental materials respectively.It would provide the valuable reference basis for the further development of potato production and breeding of potato variety with resistance to black leg.
