摘要：The research aimed to determine the growth and tolerance of M7 brown rice mutant lines against stress by application of several doses of NaCl. The research was conducted at the Bio-Science and Biotechnology Laboratory for Plant Production, Agricultural Cultivation, Faculty of Agriculture of Universitas Hasanuddin. It was conducted from October 2018 to February 2019, which was compiled based on 2 factorial design patterns and a randomized block design as it's environmental design. The first factor consisted of 9 genotypes, i.e. 8 red rice mutant lines namely g1, g2, g3, g4, g5, g6, g7, g8 and one comparison line g9 as red rice parent which was not mutated. The second factor consisted of 4 NaCl dosage levels namely 0 dS/m, 4 dS/m, 8 dS/m, 12 dS/m. The results of the NaCl treatment on several Sinjai local red rice mutant lines show that the g2 genotype had the highest average value on the parameters of the weight of the plants on a fresh and dry condition. It indicated the g2 genotype as a mutant genotype that has tolerance to salinity stress at the vegetative growth phase.
