Fusarium ear rot is a disease that cause significant yield loss in maize
globally. Breeding maize varieties with ear rot resistance by using
traditional procedures is inefficient, because the process is time-consuming
and requires great efforts in transferring resistant genes into good
hybrids. Therefore, the use of molecular markers in developing
Fusarium-resistant maize varieties is more feasible.
In a study by Huy Minh Vuong from Maize Research Institute in Vietnam and
colleagues, six SSR markers are used to select inbred lines with resistance
to Fusarium ear rot from F5 and BC5 maize populations. These markers include
Umc1025, Dupssr34, Nc030, SSR93, Umc1489, and Umc1511, which are linked to
Fusarium ear rot genes in maize plants. Results showed eleven lines positive
to these SSR markers. They selected eight lines with different marker
combinations for further breeding.
