Species of the one genus (Dioscorea)were domesticated independently in each of the three regions. Species of Colocasia and Xanthosoma(family Araceae) and Pachyrrhizus and Pueraria (family Leguminosae)were domesticated in separate regions. Many of these crops have restricted areas of distribution dueto physiological requirements and are becoming relict crops. Roots and tubers are ancient crops, and even todaysupport groups of people who gather them from wild plants. Poisonous, acrid,or bitter qualities were found in the most important crops by early man, who learned how toremove or destroy these undesirable qualities. Most of the root and tuber crops are polyploids, andmost of them are vegetatively propagated. Fertility traits are therefore of special importance in their evolution under cultivation, but there is no evidence that clonal propagation has ledto sterility. Information on their evolution is extremely scarce as cultural sources, archaeological, linguistic, and historic information is scanty and unevenly distributed. On biologicalsources, compara- tive taxonomy, metaphase cytology, and hybridization have givensome important clues, but there is still very little information available on the evolution of these species. Root and tuber crops dispersed slowly between Southeast Asia andAfrica. After the seventeenth century a very active interchange occurred especially withthe American crops. Since then, there has been a continuous replacement of crop species, especially in Africa. The sweet potato, of American origin, was found in Oceania whenthe Europeans arrived, but no satisfactory explanation of how it got to Polynesia hasever been made.

  • Micronesica 38(1):93–120, 2005
    Micronesica 38(1):93–120, 2005 Archaeological Evidence of a Prehistoric Farming Technique on Guam DARLENE R. MOORE Micronesian Archaeological Research Services P.O. Box 22303, GMF, Guam, 96921 Abstract—On Guam, few archaeological sites with possible agricultural features have been described and little is known about prehistoric culti- vation practices. New information about possible upland planting techniques during the Latte Phase (c. A.D. 1000–1521) of Guam’s Prehistoric Period, which began c. 3,500 years ago, is presented here. Site M201, located in the Manenggon Hills area of Guam’s interior, con- tained three pit features, two that yielded large pieces of coconut shell, bits of introduced calcareous rock, and several large thorns from the roots of yam (Dioscorea) plants. A sample of the coconut shell recovered from one of the pits yielded a calibrated (2 sigma) radiocarbon date with a range of A.D. 986–1210, indicating that the pits were dug during the early Latte Phase. Archaeological evidence and historic literature relat- ing to planting, harvesting, and cooking of roots and tubers on Guam suggest that some of the planting methods used in historic to recent times had been used at Site M201 near the beginning of the Latte Phase, about 1000 years ago. I argue that Site M201 was situated within an inland root/tuber agricultural zone. Introduction The completion of numerous archaeological projects on Guam in recent years has greatly increased our knowledge of the number and types of prehis- toric sites, yet few of these can be considered agricultural. Descriptions of agricultural terraces, planting pits, irrigation canals, or other agricultural earth works are generally absent from archaeological site reports, although it has been proposed that some of the piled rock alignments in northern Guam could be field boundaries (Liston 1996).

The yielded fermented yam flour ranged from 18 to 20% from crude yam tubers. The dried and fermented yam flour moisture content was around 13% and met the standards, while pH was around neutral (from 6.66 to 6.72) leading to tubers deterioration. The flour had a dark-brown color from enzymatic browning occurring during fermentation process.

McClatchey* Botanical Research Institute of Texas, 1700 University Drive, Fort Worth, Texas 76107, USA Department of Botany, University of Hawai’i at Manoa, Honolulu, Hawai’i 96822, USA Environmental Studies Program, Texas Christian University, Fort Worth, Texas 76107, USA Abstract Agricultural societies partly depend upon wild foods. Relationships between an agricultural society and its wild foods can be explored by examining how the society responds through colonization of new lands that have not been previously inhabited. The oldest clear example of this phenomenon took place about 5000 years ago in the tropical Western Pacific at the “boundary” interface between Near and Remote Oceania. An inventory of wild and domesticated food plants used by people living along “the remote side of” that interface has been prepared from the literature. This was then assessed for the roles of plants at the time of original colonization of Remote Oceania. The majority of species are wild foods, and most of these are used as leafy vegetables and fruits. The wild food plants mostly serve as supplements to domesticated species, although there are a few that can be used as substitutes for traditional staples. Keywords: Oceania, wild food plants, colonization, agriculture Introduction implication is that humans brought wild plant materials to their homes or processing sites, much as squirrels or fruit bats Human-plant co-evolutionary relationships have been might do, and then consumed less than all of the material col- documented for processes of wild plant food domestication lected, discarding material (seeds or other living parts) that into socially critical crops [1,2].

Burk. a climber plant producing tubers, belongs to Dioscoreaceae. This plant species has morphological variation on its vegetative organs (i.e. stems, leaves, and tubers). Thirty accessions of gembili were collected from Java, Sumatera, Kalimantan, and Celebes (Sulawesi) of Indonesia. Tuber samples were collected using survey methods and cultivated as a living collection. Based on IPGRI plant descriptors for Dioscorea tubers, stems, leaves, flowers, and fruits were scored and analyzed using UPGMA method. The results show that the level of diversity of gembili is quite high, ranging from 0.64-1.00 similarity values. Those accessions were divided into 2 groups: the first cultivar group has dense thorns on roots, oblong to cylindrical tuber shapes with white to yellowish-white tuber flesh. Those characters are similar to D. esculenta (Lour.) Burk. var. spinosa (Lour.) Burk. whereas the second group showed rare thorn roots, irregular tuber shapes, and violet tuber flesh color, and the characters are similar to D. esculenta (Lour.) Burk. var. fasciculata (Lour.)
