Summary.1 Certain hop plants, which were grafted in 1926 with scions either ( a ) of plants affected with the mosaic disease, or ( b ) of the seedling variety M 45 (previously proved to be a “carrier”), produced in 1927 shoots affected with mosaic disease. 2 From the evidence available, it would appear that the virus of mosaic disease can travel down a grafted stem and infect the rootstock. 3 It would appear, further, that mere contact of a virus‐carrying scion with the stock (with no growth of the former taking place) is sufficient to cause the infection of the rootstock. 4 When scions of the commercial variety Fuggles were grafted on a hop plant severely affected with the mosaic disease they remained healthy and completed their full seasonal development.
