For many years not much interest was expressed in Brassias by the plant breeders, although in more recent years
this has changed. Both inter and intra generic hybridisation has been completed, the well known breeder W.W.G.
Moir of Hawaii recording the first intrageneric hybrid in 1961. The following multigeneric combinations with Brassias
have been registered:
(List will be updated in due course)
Brassia x with the genus Aspasia = Brapasia
o Miltonia = Miltassia
o Odontoglossum = Odontobrassia
o Oncidium =Brassidiurn
o Aspasia x Miltonia = Forgetara
o Miltonia x Odontoglossum = Degamoara
o Miltonia x Oncidium = Aliceara
o Oncidium x Odontoglossum = Maclellanara
o Cochlioda x Miltonia x Odontoglossum = Belleara
o Miltonia x Oncidium x Odontoglossum = Bakerara
o Cochlioda x Miltonia x Odontoglossum x Oncidium = Goodaleara
'x Aspasia x Miltonia x Cochlioda x Odontoglossum = Schafferara
WWG Moir of Hawaii was the leader in breeding of the Oncidiinae species, including Brassias, although a number
of other breeders are developing an increasing interest in this aggregation of plants. This breeding is confined
to the Brassias in the Eubrassia Section of the genus. As many of the Brassias from the breeders point of view
have crowded flowers on rather short peduncles, Moir restricted his breeding to the two species that did not exhibit
these characteristics, namely gireoudiana and verrucosa. These, when crossed together, make the primary hybrid-Rex.
In addition to this successful cross, two other hybrids have also been used with some success: Edvah Loo (longissima
x gireoudiana) and Chieftan (longissima x verrucosa), although these two could only be utilised with
care if improvement was to be maintained. Both culturally and in breeding, some problems have occurred when plants
from two widely differing natural habitats are joined together in a hybrid. In Brassidium, some can be difficult
to grow, as the oncidiums like a quick drying airy situation with seasonal temperature variation, especially those
coming from the high altitudes, as compared with tome brassies, native of lowland habitats, and requiring more
constant environmental moisture and temperature conditions. In the use of three species, verrucosa, gireoudiana
and longissima, Carpenter notes that these combined with Brazilian Miltonias, Odontoglossums or Odontiodas
impart plant vigour and warmth tolerance to hybrids. He reports these species are dominant for flower size and
open shape, and they generally improve spike habit.
Moir reports Brassidiums are good breeders, but when they are combined with Miltonias to make Alicearas, they are
temperamental breeders. The use of the species Oncidium varicosurn has added much and provided some lovely
hybrids, but most will not breed further, often because of chromosome incompatibility, Brassia with 60, compared
with Oncidium species mainly utilised having 56 chromosomes. The Brassia x Miltonia hybrids (miltassia) using 60
chromosome species breeds easily. Experimental crossing with Trichopilias (60) and Brassia (60) plants produced
seed, but the seedlings were difficult to grow after deflasking.
In Odontobrassias, Carpenter reports, the Brassia shape is strongly inherited in this intergeneric. He also reports
Degamoaras are usually made with a Miltassia including a Brazilian Miltonia.
Brapasia (Brassia 60 x Aspasia 56 chromosomes) took up to chromosome number of one or the other parent. These hybrids
took a long time for the pod to ripen (280 - 300 days even for green pod culture) this being a characteristic of
nearly all Brassia crossings. The introduction of Miltonia into the hybrids shortens the ripening time. Moir also
reports that Brassia hybrids seldom can be used as males, not even with one of their own kind. Most will however
take species as the male while refusing hybrids.
With Aliceara (Brassia x Miltonia x Oncidium) Moir states these are more easily made from a Miltassia and a Miltonidium
than from a Brassidium and a Miltonidium or even a Miltonidium and a Brassia.
