Kristian Theqvist, Finland, 5b
Based on the Pollen-to-Seed Program Mr. Theqvist formed in 2007 a small hybridizer team in Finland. The results in 2007 were good and the hybridization work was continued in 2008. The two other hybridizers in addition to Mr. Theqvist were Osmo Jussila from Naantali and Jaakko Saarinen from Arboretum Mustila. To optimize the amount of seed we made R. brachycarpum ssp. tigerstedtii crosses with two separate plants, one at Naantali and another at Arboretum Mustila. The seed batches were merged before sending to ARS.
The main aim in the hybridization program was to to get hardy reds by using the super hardy R. brachycarpum ssp. tigerstedtii and hardy proven Finnish hybrids as seed parent and pollen from Rhododendron species with red flowers. In addition there were side goals for beautiful leaves and good indumentum. As a special there are seeds from a R. brachycarpum Korean form, cross-pollination between 5 plants, collected 1976 in South Korea as R. fauriei var. rufescens.
