At the International Rose Trials of Nyon, Switzerland, 33 medals have been awarded to breeders from different countries on June 20, 2020. The notion of 'zero spraying' makes the trials special and the 13 awards harvested by The House of Meilland and its partner breeder is therefore the crowning glory of their many years of work. In this article, they tells us more about their long involvement and investment in selecting varieties in zero spray conditions since the late 70’s.

Many years of work

Zero spray trials in the south of France

In order to breed for stable, horizontal and vertical disease resistance and because of the diversity of diseases and disease strains, The House of Meilland designed a private testing system in gardens installed in different climatic conditions: two in France, two in the USA and one in Germany.

"From USDA Zone 9 in a Mediterranean climate that shows variety sensitivity to rust and mildew, to USDA Zone 6 in a Continental climate that shows variety sensitivity to black spot and cold hardiness, we are covering most problems that can occur", he says.

Those tests are replicated in climates as cold as Astana, Kazakhstan (USDA Zone 3) and as warm and humid as Shenzhen, China (USDA Zone 10).

"This is how The House of Meilland can enter world trials in zero spray conditions and gather so many prizes."
