By dividing the factors that cause corn disease into different groups,an experiment on the anti-rust was carried out in the plant protection field of the Baicheng Academy of Agricultural Sciences,in which 104 corn species were tested.In the experiment,30 high anti-rust species or hybrids and 20 anti-rust species or hybrids were selected.39 species or hybrids were susceptible to rust and 15 species or hybrids were highly susceptible to rust.This could provide reference for the anti-rust corn breeding and agricultural production.
