Abstract

High Yielding Coconut Tall Varieties Specific for Gorontalo The major constraint for coconut development program in Indonesia, including Gorontalo Province is the lower crop productivity i.e merely 1 ton copra/ha/year. Increased coconut production and productivity must be done hand in hand with coconut replanting program. To support the program, the use of high quality planting material is required. There are two options available in this matter. First, by utilizing the available coconut tall high yielding varieties suitable for agroclimate similar to Gorontalo (dry climate). Second, or most preferably, utilizing the high yielding local tall coconut cultivars. Preliminary evaluation by local estate officer indicated that there are some local coconut tall cultivars (ca. 4 cultivars) that had both high yield and oil content. This research was therefore aimed at further assessing these four promising local cultivars. Evaluation was done on those pre-determined populations in two phases, for three years consecutively, from 2006 to 2008. Parameter observed include morphological, yield of copra and its components, physiological and chemical characters as well as field resistance to pest. Results of evaluation, conducted by the ICOPRI and Dishutbun Gorontalo, confirmed that two cultivars, namely, Kelapa Dalam Molowahu (DMU) and kelapa Dalam Kramat (DKT) could be considered as two high yielding cocconut tall cultivars specific for Gorontalo. These two cultivars exhibited high productivity (above 3 ton copra/ha/year) and possess high oil content (above 64%). These cultivars have formally been released as new varieties by Minister of Agriculture in Desember 2009, to be used for high quality planting material for coconut development program in Gorontalo.

Abstract

Exploration of Sugar Palm (Arenga pinnata Merr) Germplasm in East Kutai, East Kalimantan Province To broaden the genetic base of the plant, in December 2009 a mission to acquire new germplasm of sugar palm was sent to East Kutai District, East Kalimantan Province. The target location was the village of Teluk Pandan, Kandolo sub-District and village of Peridan, Sangkuliran sub-District. Mission successfully identified two types of sugar palm; dwarf type from the Teluk Pandan village, Kandolo sub-District and Tall type from Paridan village, Sangkuliran sub-District. Dwarf type is observed to have high variability in term of stem height, stem length, male inflorescence, length of male peduncle, number of males inflorescence, number of female inflorescence and time period of sap production per bunch. While Tall type has high variability in term of stem height, length of male inflorescence, the number of male inflorescence, female inflorescence, stem length, number of female inflorescence, production of sap, and period of sap producing.
