Black rice mutant strain selection results of M3 generation mutation breeding

Abstract

Local rice is germplasm which has great potential to be developed in meeting food needs in Indonesia. Black rice is known to have great health benefits but in general has a weakness in low yields. Therefore, research is needed to overcome this weakness. This study aims to determine the effect of heavy ion beam irradiation on production yields per hectare of the black rice mutant lines of the M3 generation. The experiment was carried out for 6 months using 50 strains of black rice mutants obtained from the M2 generation plus 1 negative control and 1 positive control. Based on the results of the coefficient analysis on the observed characters, there are potential and effective characters to be developed in the next M4 generation of black rice, namely the number of grains per panicle, panicle density, panicle length, percentage of filled grains per panicle and 100 grains weight.
