520 _aCrops were established through landraces which were selected from wild spedes of plants by farmers. The landraces have been subjected to hybridization with wild relatives and mutations. Weedy forms of crop spedes, which are characterized as intermediate types between cultivars and wild species, are products of continuous changes of genetic compositions of crop species. The populations of wild types are genetically heterogeneous in various genotypes whereas cultivars are relatively homogeneous (Allard 1989). The Korean rice collection is composed of weedy forms, landraces and bred varieties. The weedy forms of rice in Korea were divided into four different groups based on Japonica, Indica and their combinations with wild relatives, arising from out-crossing events by isozyme and random amplified polymorphic DNA markers (Cho et al.1995; Suh et al.1997). This study was conducted to develop DNA finger-prints of Korean rice collections. This genetic information might reveal the phylogenetic relationships between landrace, weedy rice, and bred varieties.
