There are two recognized types of coconut varieties: the a) dwarf and the b) tall variety. These are simply distinguished according to its height. Dwarf coconuts are usually early maturing. It produces nuts during its earlier years compared to the tall varieties. Tall varieties however yield more nuts than dwarf varieties. Description of some studied coconut varieties are indicated below:

Nomenclature and Description of Some Selected Coconut Varieties.
VARIETYCODEORIGINDISTINGUISHING FEATURES
TALL
West AfricanWATIvory coastNuts are distinctively angular and ridged at equatorial region; high nut producer often exceeding 100 nuts per year; homogenous; good GCA with MYD
RennelRITSolomon Is.Very precocious palms with generally pear-shaped nuts; long peduncle and good fruit composition; copra per nut is 300 grams; very homogenous and uniform; good GCA with MYD and MRD.
BaybayBAYPhilippinesCopra per nut is quite heavy although nuts do not really look big; very thin husk; homogenous and produces high number of leaves per year; bunches with short peducle and nuts are trapped between leaf axils; stem quite robust and firm; tolerant to FDMT.
San RamonSNRPhilippinesUsually bears extra large nuts when young needing 3 to 3.5 nuts per kilo copra.
TagnananTAGPhilippinesProduces nuts with good fruit corn position; 350 g copra per nut and very homogenous; good GCA with MRD
TahitiTATTahitiHigh nut producer (116 per year); very heterogeneous and susceptible to leaf spots
Markham ValleyMVTPapua New GuineaVery robust trunk; big nuts with very thick husk
Gazelle Peninsula TallGPTPapua New Guinea
VanuatuVTTVanuatuProduces many but small nuts and resistant to FDMT
LagunaLAGPhilippinesProduces a fairly large number of nuts; 190 g copra/nut; hybrid cross with CAT green dwarf good
Andaman GiantAGTIndiaA strong and robust palm showing gigantic features. Leaves are long, petioles are long and thick, leaflets are long and wide. Nuts are very large and round with about 190g copra/nut. No toddy yield.
BaliBATIndonesiaFruits are large and round, unhusked nuts prominently flat-bottomed with pointed posterior. Copra per nut is 200 to 300g with some having as high as 450g.
JamaicaJAMJamaicaSlender palm with slightly curved stem covered with rough leaf scars. Fruits are oblong and large, angular, green or brown with thick husk and shell. Late germinating in the Caribbean Islands and Atlantico Alto.
BodiriBDRSri LankaBears 50 to 100 small nuts per bunch, copra per nut very low at 50g needing 20 nuts for a kilo of copra. Same as Maphrao-Phuang in Thailand.
AgtaAGAPhilippinesHusk of nut is streaked, making it look around and tough. Young nuts show black streaks
LaccadiveLCTIndiaSimilar to West Coast Tall (WCT) except for high oil content (72%). Nuts are medium sized and high yielder of toddy. Flower production and setting percentage are high.
MalayanMLTMalaysiaRobust palm with round stem and large bole. The base of the button has a rose-ring which can be seen clearly when perianth is removed. Large spherical fruit has a thin shell, sweet aromatic water and an average of 275g copra.
MacapunoMACPhilippinesA mutant form of the Laguna variety, nuts have soft and jelly-like meat. This character is lethal to the embryo which needs to be grown in artificial medium. Naturally occurring palms grown from normal nuts bear about 25%. MAC nuts may give 100% macapuno nuts.
Igoh DukuhIGDIndonesiaNuts have very thin husk and the shape of the shell conforms to the shape of the whole nut all the way. Shows high biennial bearing tendency.
DWARF
CatiganCATPhilippinesNuts are medium sized, round with prominent stigmatic tip; copra per nut is about 200 to210g; husk is thick; peduncle and bunch rachis are long; young nuts and petioles are green.
CoconinoCNOPhilippinesNuts are very small, oblong and smooth; stem quite thin and high yielder of toddy. Copra per nut seldom exceeds 100g. Coconino is a green dwarf.
KinabalanKINPhilippinesGreen dwarf, nuts are extra large, robust stem and copra per nut sometimes exceeds 300g; homogeneous.
PilipogPILPhilippinesNuts are green and round; female flowers, tip of roots and base of shoots of newly germinated seedlings are pink; copra per nut is 100g.
TacunanTACPhilippinesAnother green dwarf; spikelets are very short; nuts are medium to large oblong with broad equatorial diameter and pointed stigmatic; and unopened spathes are flat on distal end.
AromaticAROThailandLeaves are short with wide leaflets; male flowers are small and numerous; nuts are deep green when immature; sweet water and meat; mature nuts show a navel at the eye when split-opened.
Brazilian Green dwarfBGDBrazilVery marked dwarfism; good fruit composition; nuts are rounder but much smaller than CAT or TAC nuts
Sri Lanka Green dwarfSGDSri LankaNuts small and prominently long with protruding stigmatic tip; strictly autogamous with numerous female flowers.
Malayan Yellow DwarfMYDMalaysiaHybrid cross with WAT called WAWA is high yielding; young nuts and petioles of leaves are yellow; great tendency for alternate bearing; nuts with thin husk and low meat content; autogamous; sensitive to Phytoptora fruit rot
Malayan Red DwarfMRDMalaysiaYoung nuts and petiole of leaves are bright orange; nuts thicker; self-pollinating; cross with RIT, TAG and BAY are very promising; sensitive to Phytoptora fruit rot
NiulekaNLAFijiLocal green dwarf variety of Fiji with very short internodes and very dense crown; short, rigid leaves with closely-spaced wide leaflet and short stubby spadices. Predominantly cross-pollinating with large fruits.
Chowgat Orange DwarfCODIndiaFound in Central kerala, COD is early bearing and produces medium-sized orange colored nuts with 135g copra. This variety retains unfertilized female at spike.
MangipodMGPPhilippinesA green dwarf which retains hundred of ripe nuts on the crown due to drying of nuts on the tree. Highly self-pollinating and shows very strict dwarfism.
GangabondamGGBIndiaAn intermediate variety which breeds 96% tru-to-type although showing a mixture of dwarf and tall characteristics; shows considerable variability in copra per nut rangin from 150 to 230 g with high oil content of 72%.
King Coconut (Gon Thembili)GTBSri LankaMost famous coconut of Sri Lanka known for its high quality water. Shows a bole and somewhat larger trunk than dwarfs but highly self-pollinating.
SpicataSPI
Produces unbrached inflourescences with more female flowers than male; may occur in tall or dwarfs and when open-pollinated, some may produce unbranched inflourescence while others may not.
TampakanTMPPhilippinesNuts are long and pointed. Shape of shell and cavity conforms exactly to the shape of inhole nut which has a very thin husk.
