Summary
The extreme resistance to ryegrass mosaic virus (RMV) of a clone of Lolium perenne L. was due to a combination of two distinct types of resistance: resistance to infection and resistance to multiplication and movement of virus within the plant. Resistance to infection was quantitatively inherited and highly effective against three strains of RMV, while resistance to multiplication and movement was controlled by two complementary recessive genes and was effective against only two of the three RMV strains.
