Diversity of Some Indonesia Local Glutinous Rice (Oryza sativa L. Var. Glutinous) Based on Agromorphological and RAPD Markers



Ketan is a term for glutinous rice in Indonesia that is widely used as an ingredient in various traditional dishes or desserts. However national production of this plant is low because most of the farmers prefer to cultivate paddy. This research aimed to investigate genetic diversity of potential parents. These results will be used to create new varieties of glutinous rice. The plant materials used in the experiments included eight local upland glutinous rice cultivars from West Java, Banten, and Bengkulu province. The seeds were planted by drill seeding in the experimental plots. The observations were recorded on quantitative and qualitative characters of each cultivar. The results showed that cv. Pisitan Bulu and cv. Ketan Hideung had high values for seed weight (above 3 g/100grain), with plant height around 180 cm, long maturity (97.5 DAP for 50 persen flowering), and low tiller number (less than 10 tillers/clump). These weaknesses can be overcome by cv. Hitam-46 and Kelapa (plant height < 120 cm, tiller number > 20 tillers/clump and 50 persen flowering around 75 until 80 DAP). Almost all cultivars were resistant to blast disease. The results suggested that Pisitan Bulu, Ketan Hideung and Ketan Hitam-46 could be used as potential as parents in breeding programs. The results of this research indicated that the use of RAPD markers combined with agromorphological traits are useful for identifying genetic diversity of glutinous rice. Based on the dendogram from genetic analysis, qualitative, and quantitative characters, Ketan Kelapa and Ketan Hitam-46 were similar even though the origin was different (Ketan Hitam-46 from West Java, Ketan Kelapa from Enggano Island, Bengkulu Province).
