The OSU selections.
A number of selections from the Oregon State University breeding programme were imported on the recommendation of Prof. Maxinne Thompson.
For many years these were referred to as the “Maxinne Thompson” or “MT” selections.
Only two have been propagated for sale, OSU 14-84 and OSU 18-114.
Three other selections are present in the Wairata or Lincoln collections.
