Indonesian sugarcane germplasm collecting expedition - 1984.

Abstract

A sugarcane germplasm collecting expedition was conducted in the Indonesian Archipelago from June to August 1984. Collections were made in northern Sumatra, Sulawesi, the Maluku Islands and Irian Jaya. Some 133 accessions were collected, representing Erianthus, Miscanthus, and all recognized species within the genus Saccharum. Diseases frequently observed during the expedition were red rot [Glomerella tucumanensis], rust [Puccinia melanocephala], yellow spot [Mycovellosiella koepkei], brown spot [Cercospora longipes] and mosaic [sorghum mosaic potyvirus]. The area in which the greatest level of genetic diversity was found was between Parigi and Lake Poso on Sulawesi. An abundance of Erianthus, Miscanthus, S. robustum, S. spontaneum and hybrid clones were intermixed throughout this area. As of 1990, 48 clones collected during the expedition were reported to be in the world collection at Miami, Florida. An appendix details the clones collected.
