I probably have 40-45 different hybridizers represented, and 21 are Dykes medal winners.
I really didn't pay much attention to hybridizers until a few years ago. I'm not surprised Schreiner is first. I've been ordering from them since the 80's, and they've been in business longer that any of the other folks. I suspect things will shift some in the coming years.
