Abstract: For screening waxy maize germplasm and waxy variety with the resistance of maize rough dwarf virus, 64 waxy maize inbred lines and 25 waxy maize hybrids commonly in production were tested for reaction to maize rough dwarf virus (MRDV) under field conditions in two years. The results showed that 60% of the inbred lines and hybrids were sensitive or high- sensitive to MRDV, and the resistance to MRDV was significantly different between different years, different cultivars and between the same cultivar in different years; inbred lines belong to T5 group had better resistance to MRDV than other three groups; two waxy hybrids were identified as resistance to MRDV.
