Abstrak

Local rice is a potential germplasm as a source of genes that control important properties in rice plants. The research aimed to characterize the morphological character of local rice cultivars of North Sulawesi. The research was conducted from January to June 2015 in North Sulawesi. The method used was the descriptive qualitative method. Exploration was done by collecting samples of local rice cultivars in North Sulawesi. Each cultivar was characterized its morphological characters according to the Characterization and Evaluation Guidelines of Rice Germplasm. The local rice found in North Sulawesi were 10 varieties, namely Pulo Sawah, Superwin, CK, Serwo, Pilihan, Sako, Sito Merah, Sito Putih, TB, and Serayu. There were similarities of the characters from all local rice varieties of North Sulawesi, such as culm (culm strength and culm habit), leaf character (basal leaf sheath color, leaf blade color, collar color, and auricle color), and flower character (panicle exsertion and panicle attitude of branches). The character of grain morphology was very diverse for all local rice varieties of North Sulawesi.
