A genotype becomes eligible for registration under the Act if it essentially fulfils the criteria of Distinctiveness,
Uniformity and Stability (DUS) which means that the candidate genotype must be distinguishable by at least one
essential characteristic from a genotype of common knowledge in any country at the time of filing application,
sufficiently uniform in expression of its essential characteristics which should remain fixed even after repeated
multiplication. The genotype should also have a single and distinct denomination (Greef, 2008).
Mokara
hybrids showing significant variation in morphological vegetative and floral characters could be used as
parents for developing new hybrids.
Vanda
‘Miss Joaquim’ is said to have taken the form of
V. hookeriana
and the
colour of
V. teres as reported by
Fuchs R.F. (1997) and Tim Wing Y.T. (2001) reported that
Vanda sanderiana
and
V. coerulea
are the two important vanda species found in the background of most of the vandaceous hybrids.
V.
sanderiana
gives full form, whereas
V. coerulea
imparts the rich blue violet colouration, lobely tessellation as well
as the long inflorescence. Examples of Vanda hybrids exploited as parent plant for evolvement of new hybrids are
“Amoene’, ‘Betsy Summer’, ‘Bull Sutton’, ‘Eisenhower’, ‘Ellen Noa’, ‘Emily Notley’, ‘Ernest’, Fujinaga’,
‘Frank Crook’, ‘Haledena’, ‘Helen Reynolds’, ‘Hilo Blue’, ‘Honolulu’, ‘Jennie Hashimoto’, ‘Josephine Van Bero’,
‘Kapolio’, ‘Manila’, ‘Manisaki’, ‘Miss Joaquim’, Noel’, ‘Nora Potter’, ‘Norbert Alphanso’, Onomea’, ‘Poepoe’,
‘Rubella’, ‘Ruby Prince’, ‘Tan Chay Yan’, ‘Tatzeri’, ‘Trimerrill’, ‘Trisher’, ‘Venus’ and ‘Waipuna’ (De and
Bhattachrjee, 2011).
