Bamenda (Special variety)
The genetics of the Bamenda variety refers to advanced generations of the variety formerly known as Bamenda x Ekona, whose maternal lines were developed in Costa Rica from wild materials from the highlands in the region of Bamenda, Cameroon (altitude about 1,200 m above sea level).
Bamenda commercial seeds come from the second filial generation (F2) of mother palms developed in Costa Rica. These mothers are crossed with fathers descending from the Ekona population, whose selection and initial breeding process was carried out in Cameroon from where it was introduced to
Costa Rica in 1970. At present, we use pisifera parents from the first and second generation of breeding carried out in Coto, planted between 1987 and 2010. The Bamenda variety has moderate vertical growth (55 cm/year), but because it has normal length leaves it is planted at the conventional density of 143 palms per hectare. Its bunches have small fruit (6 g), with a moderate oil content. The Bamenda palms tolerate stressful conditions quite well, particularly low temperatures and drought.
Therefore, they are often planted in areas up to1,000 m above sea level. In addition, this variety shows good tolerance to the Common spear rot/crown complex and in areas affected by bud rots, it has shown a low rate of increase of that disorder, mild symptoms and a fast recovery. It has also shown good tolerance to the disease known as sudden wilting (Phytomonas sp.).
