Yield quality and performance of three strains black rice from gamma ray irradiation

Abstract

Black rice is one of the local Indonesian rice varieties contains high anthocyanins. This research used the treatment of three different strains resulting from gamma ray irradiation (strain 8, 44 and 51) and control (without irradiation). The data was analyzed descriptively and qualitatively to compare three strains of black rice irradiated by gamma ray with control (without irradiation). The result showed that the three strains of black rice "Cempo Ireng"irradiated by gamma ray had better yield quality and performance compare to control (without irradiation). Strain 44 was the strain with the highest anthocyanin content of 75.11 ppm and the best performing strain (organoleptic score of 3.53 and seed pericarp color of 4). Strain 51 had the best amylose content (8.43%), the highest protein content (7.48%), the highest fat content (1.59%), the best vigor (80%) and seed viability (64%).
