Abstract
<p>Wild rice spesies is relative<br />of cultivated rice and has many differences of its characteristic.<br />Morphological characteristic variation on crop can be used as<br />working assets in breeding program. Morphological<br />characterisation was conducted in three planting seasons in<br />2004 until 2005 at Indonesian Center for Agriculcural<br />Biotechnology Research and Development green house<br />consisted of 88 accessions of 18 wild rice spesies which<br />belonged to 4 groups of Oryza spp. (Oryza sativa, O.<br />officinalis, O. meyeriana, and O. ridleyi). The characteristic<br />observed were include 12 quantitative characters and 5<br />qualitative characters with 23 subcharacters. The wide of<br />quantitative morphological character variances were found in<br />plant high, tiller number, days of flower, total number grain/<br />panicle, awning length and stalk diameter, while the narrow<br />character variances were found in panicle length, 1.000 grains<br />weigth, grain shape, total internode and internode length. The<br />qualitative characters variance were found in grains, stalk,<br />ligule and leaf morphology, while panicle morphology of wild<br />rice species was dominated by open panicle type, erect panicle,<br />secondary branching were absent and well exserted.</p>
