Selection of new genotypes adapted to cold zones and water deficit
ASD has a long tradition in the development of new oil palm varieties adapted to different environmental conditions. Currently there are two field trials in areas located at 1,200 and 900 meters above sea level in the mountainous region of San Vito in southern Costa Rica. The climate of the higher altitude site is characterized by high rainfall, while the other has a defined dry season. A repetition of the genotypes under evaluation was planted in the Coto area a few meters above sea level. The four varieties planted were Deli x Ghana, Deli x Nigeria, Bamenda x Ekona and Tanzania x Ekona.
The production of bunches in these experiments began a short time ago, but it has been observed that in the high zones, vegetative growth and the initial yields are better in the Bamenda x Ekona and Tanzania x Ekona varieties. The mother palms of these varieties were originally selected in the highlands of the regions mentioned in Africa. However, in the lower zone (Coto), where the breeding program is located, the vegetative development of the four varieties has been better and bunch production started earlier. In these conditions, which are more appropriate for oil palm growth, the four varieties have performed similarly. We will keep you informed about the progress of these trials.
