在对我国木薯主栽区的调查中发现,疫霉根腐病在云南、海南、广西、广东等地普遍发生,已经成为木薯产业中一个值得关注的新问题。采用室内离体接种法进行了59份木薯种质的抗性评价,结果发现仅有6份种质为高抗,占10.20%,11份种质为高感,占18.64%,大部分种质均表现出一定程度的感病性。田间活体接种进一步证明SC11为高抗,而GR4为高感。

The survey for cassava root rot of Pytophthora palmivora was finished in our research, and this disease widely happened in Yunnan, Hainan, Guangxi and Guangdong provinces, which had became a new important obstacle of cassava industry. Using in vitro inoculation method in lab, the resistant evaluation of fifty-nine cassava germplasms was finished. The results showed only six kinds of germplasms were high resistant and the proportion was 10.20 %, eleven kinds of germplasms were high susceptible and the proportion was 18.64 %. Most of the germplasms showed certain degree of susceptibility. The vivo inoculation result confirmed cassava germplasms SC11 was high resistant and GR4 was high susceptible, and this test was studied on living plants in field.
