Abstract. Nilahayati, Nazimah, Handayani RDS, Syahputra J, Rizky M. 2022. Agronomic diversity of several soybean putative mutant lines resulting from gamma-rays irradiation in M6 generation. Nusantara Bioscience 14: 34-39. Soybean is one of the foremost commodities for Indonesian people. Therefore, increasing domestic production absolutely must continue to be pursued. One way that can be done is to use the assembly technology of new superior varieties with better and adaptive properties. This study aims to determine the agronomic diversity and yield of soybean putative mutant lines resulting from gamma irradiation in M6 ??generation. The research was conducted in Paloh Lada Village, Dewantara District, Aceh Utara Regency, Indonesia, from July 2021 to October 2021. The tested genotypes consisted of 8 genotypes, namely Kipas Putih variety (parent variety), Anjasmoro variety (comparison variety), M.1.1.3, M.5.2.1, M.5.2.3, M.1.1.8, M.1.1.9 and M.1.1.17 mutant lines. The results showed that the agronomic diversity of the tested mutants was different compared with the parents and comparison variety. We obtained early maturity and high yielding mutant in M7 ??generation. The mutant lines with high yield and equivalent to its parents was M.1.1.8 with a production of 4.37 tha-1. Mutant lines with early maturity were M.1.1.9, M.5.2.1 and M.1.1.3 lines with a harvesting age of 83 days after planting (DAP).
