DISCOVERY AND CHROMOSOMAL LOCATION OF A NEW RESISTANCE GENE TO Maize dwarf mosaic virus STRAIN B;

A new resistant elite inbred line Siyi was identified with resistance to maize dwarf mosaic virus strain B at early and adult stage.

20 highly resistant materials and 25 resistant materials to maize dwarf mosaic virus were screened from 81 maize inbred lines by rubinoculation.

This report discused the origination of primary infection,disease symptom and resistant hereditory feature of MDMV.

Study on the strain identification, host range and helper component of MDMV;

Maize dwarf mosaic virus(MDMV) is wildly distributed in the whole world.

The MDMV(Maize Dwarf Mosaic Virus, MDMV) CP (Coat Protein, CP) gene was cloned by RT_PCR method and introduced into the embryonic calli derived from immature embryos of elite inbred 18_599hong and 18_599bai via particle bombardment.
