ABSTRACT:
Botanical classification:
Curcuma hybrid.
BACKGROUND OF THE INVENTION
The present invention is directed to a new and distinct cultivar of Curcuma, botanically know as
Curcuma hybrid,
and having the cultivar name ‘Laddawan’.
The new cultivar was a seedling among a progeny of
Curcuma alismatifolia×Curcuma
cf.
cordata,
selected by the inventor.
Asexual propagation of the new cultivar in Nakhon Pathom, Thailand by division and micro-propagation has demonstrated the uniformity and the stability throughout successive generations of this new Curcuma.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed in the new cultivar grown under 50% shade condition in Nakhon Pathom, Thailand which closely approximate those commonly used in commercial horticulral practice.
The features that in combination are believed to distinguish ‘Laddawan’ from other known cultivars of Curcuma include: long peduncle; purplish pink coma bracts, obovate bracts; oblong ovate leaves.
Plants of the new Curcuma can be compared to plants of the
Curcuma alismatifolia
‘Chiang Mai’ (Unpatented) which are popular in the world market. Plants of the new Curcuma differ from plants of the cultivar ‘Chiang Mai’ in the following characteristics:
1. The labellum of the new Curcuma floret is yellow, instead of blue as found in ‘Chiang Mai’.
2. The coma bract of the new Curcuma is elliptic and spacing apart from each other, instead of obovate and closing together as found in ‘Chiang Mai’.
3. The leaf of the new Curcuma is oblong ovate, instead of elliptic as found in ‘Chiang Mai’.
4. The lateral vein of the new Curcuma is pronounced, instead of diffused as found in ‘Chiang Mai’.
