Relationship pattern and morphological characterization of brown rice in Munte and Payung Subdistrict, Karo

Abstract

Brown rice is known to be a good source of antioxidants, due to the presence of anthocyanin pigments that produce antioxidants, which makes it very well consumed because it can brownuce the risk of diabetes and other degenerative diseases. The aims of this research are to characterize morphology, determine kinship patterns, and anthocyanin content from brown rice (Oryza nivara L.). The study was carried out in Munte and Payung Subdistricts, Karo District. Descriptive survey method uses the International Rice Research Institute (IRRI) guide. The technique of determining the location intentionally and sampling by chance. The most dominant differences in morphological characters in brown rice in the three land locations in two sub-districts are the flag leaf shape, panicle appearance, age of flowering, grain length, rice shape and colour of the rice. The anthocyanin content test used analytical methods by homogenizing the sample. Exploration results obtained 72 accessions divided into three land locations. Based on the test of anthocyanin content obtained land A has the highest content of 0.5 mg/100 g and the lowest is B area of 0.08 mg/100 g.
