First and foremost, I have not yet known any new hoya variety released in the Philippines as a result of artificial pollination done either by ornamental breeders in any research institution or by amateur breeeders. I also haven’t succeeded in developing new hoya hybrids thru artificial breeding.
Unlike in other countries, particularly U.S.A., new hoya hybrids are produced and released every year due to active hoya breeding programs mostly done by amateur breeders. As of January 1, 2006, 13 hybrids were listed with the International Hoya Association (Fraterna Volume 19, Number 1). Michael Miyashiro is one of the famous hoya breeders who developed Hoya Kaimuki by artificially crossing H. archboldiana and H. macgillivrayi. This is just one of the many hoya hybrids he developed.
