Supreme (High density variety)

The genetics of the Supreme variety refers to advanced generations of the variety previously known as Deli x Compact, which comes from the crossing of Deli dura palms (Bogor, Java) with compact pisifera palms, originated from the successive backcrossing of a natural E. oleifera x E. guineensis hybrid with E. guineensis.

Commercial seeds of the Supreme variety, come from the third and fourth filial generations (F3 and F4) of the Deli dura population introduced from recognized breeding centers such as MARDI (Malaysian Agricultural Research Institute), Chemara Research Center and Banting Research Station in Malaysia, DAMI in New Guinea and SOCFIN in Indonesia. The current mother palms were planted between 1996 and 2008.

These advanced generation mothers are crossed with father (pisifera) descendants of a reduced growth population, originally known as a compact population, exclusive to ASD, which were planted in Coto between 1996 and 2008. Currently, ASD uses superior pisifera parents from the second and third generations of breeding carried out in Costa Rica.

Supreme palms are characterized by having shorter leaves and trunks than common E. guineensis varieties, so they can be planted at higher densities than conventional palms. Their bunches are rounded and well-formed with large fruits (13 g) and have a very high oil content.

Like the other high-density varieties, Supreme is very precocious and fresh fruit production commonly exceeds 30 tons by the third year of harvest under favorable management, soil and climate conditions. In smallholder plantations in Thailand with irrigation and good agronomic management, with some frequency you can obtain productions of up to 40 tons of fresh fruit per hectare in the fifth year of harvest with this variety. The suggested planting density for this variety is 160 palms per hectare.
