To complete the 2011 period of KKP3T Project on Kopyor Coconut, Ismail Maskromo (PhD/S3 Graduate Student at PMB Lab, IPB) and Prof. Sudarsono went to Pati and Solo, Central Java. The purposes of this visit were to record the rate of success for conducting controlled cross-pollination in Kopyor coconut, to plot the experimental site to test the effect of pollen sources to the success of producing Kopyor coconut fruits, to harvest samples of Kopyor coconut fruits from selected coconut provenance (Location at Pati, Central Java), and to check on the ex-situ censervation of Kopyor Coconut (Location at Klaten, Central Java). Ismail Maskromo stayed in Pati, Central Java all days during the visit period while Prof. Sudarsono stayed in Pati for one day and visit to conservation site at Klaten, Central Java before going back to Bogor.
We went to Pati, Central Java at November 11 – 14, 2012. The first site to visit was Kopyor coconut garden belonging to H. Masykuri. A number of experiments were set in his garden, such as: effects of controlled cross-pollination in Kopyor coconut and effect of pollen sources to the success of producing Kopyor coconut fruits.
Based on the field observation, the rate of success for cross-pollination in Kopyor coconut is still rather low in some cases. However, this probably because the pollination techniques is still being standardized. Based on these results, the cross-pollination techniques still need some improvement, especially in determining accurately the receptive periods of female flower and the amount and frequency of depositing pollens to the female flowers. One or two rounds of other cross-pollination may be needed to get better understanding on the effects of controlled cross-pollination on Kopyor coconut fruit yield.
On the effect of pollen sources experiment, in this visit we verify the existence of Kopyor coconut provenance in the gardens as the potential male parents and select a number of them as the female parents. From these provenance, a number of Kopyor coconut fruits and leaf samples have been harvested and sent to Bogor for genotyping analysis using SSR markers.
For the ex-situ conservation of Kopyor coconut, the growth and development of Kopyor coconut seedlings at the conservation site – Klaten, Central Java were evaluated. At this site, Kopyor coconut was grown in mix cropping with corn and other crops. Importantly, the Kopyor coconut seedlings grows normally in the conservation site.
This visit may be our last visit to Pati, Central Java in 2011 under the KKP3T Project. We hope that there will be funding for Kopyor coconut activities in Pati, Central Java in the year 2012 and beyond.
