| Abstract: | In order to determine the resistant level of maize varieties to be introduced to Guangxi on major diseases prevalent on Guangxi maize production area, the resistance identification of 6 major diseases to 62 maize varieties which belong to tropical and subtropical or southwest China spring maize growth types was proceeded in 2016-2019. The results showed that the ratio of moderate resistance or above to banded leaf and sheath blight, southern maize rust, northern leaf blight, southern leaf blight, fusarium and gibberella ear rot and fusarium and gibberella stalk rot were 27.9%, 30.6%, 66.1%, 50.0%, 68.9%, 69.4%, respectively among all the maize varieties; the resistance of different years on the same varieties showed some similarity, except in a few years; the ratio of varieties showing susceptible and highly susceptible to banded leaf and sheath blight and southern maize rust were higher than 4 other diseases, both of which exceeded 60%;and when varieties were grouped by provincial source, the results were similar, that is the ratio of susceptibility and high susceptibility to banded leaf and sheath blight and southern maize rust were much higher than other 4 diseases. The identification results indicated that while selecting varieties introduced to Guangxi from other provinces located on the same ecological area, it requires great attention to avoid introducing varieties with highly susceptible to banded leaf and sheath blight and southern maize rust, thus damage caused by diseases could be avoided or relieved, production of introduced varieties could be secured. |
