Montreal Botanical Garden trial results

On HFM, I see this sometimes: "In September 1998, the Montreal Botanical Garden (Le Jardin Botanique de Montreal) carried out a survey of its roses' resistance to black spot, powdery mildew and rust. This is one of the outstanding varieties which showed a 0% to 5% infection rate. The data were taken on well-established roses."

And also this: "One of the Roses that "passed the test" in Longwood Garden's Ten-Year Rose Trials."

Does anyone have the full results of the Montreal Botanical Garden or Longwood Garden trials? I'd like to see what other roses passed the trials.
