Abstract

The tall form of coconut, San Ramon was imported to Sri Lanka from
the Philippines and was first established in the North Western Province. The
open pollinated seed obtained from the first introduction and planted at the
Coconut Research Institute (CRI), form the genetic base for San Ramon
improvement at present. This cultivar inherits the potential of producing 51 %
more copra per nut than Sri Lanka Tall palms and 50% more copra per nut
than the improved tall, CRIC 60. The mean copra yield per nut recorded for
San Ramon (selfed), Sri Lanka Tall and CRIC 60 was 371 g, 240 g and 246 g
respectively. Preliminary investigations have shown that the oil extraction
efficiency of copra is 776 ml per kg of copra for Tall x San Ramon whilst for
both Sri Lanka tall and CRIC 60, it is 740 ml. The results of this study
strongly justify the use of San Ramon and its crosses for copra and oil
industry in Sri Lanka.
