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).

Performance of F2 Generation Lines of Soybean (Glycine max. L) as Backcross Results of GHJ-4 and GHJ-5 with Ryoko as A Donor Parent

“…The yield character is a complex character that is heavily influenced entirely by the character of the components of the yield gene. The yield components are controlled by many genes in which expression is heavily influenced by the environment (Nilahayati et al, 2022). The weight of seed per plant is one of the yield characteristics that can increase the productivity of the overall soybean yield in addition to other yield characteristics.…”

Induction of genetic diversity in gepak kuning soybean cultivar and M.1.1.3 line using ethyl methane sulfonate in M1 generation

“…In the past, gamma rays have been used by several researchers on various soybean genotypes. For example, the Argomulyo variety was exposed to gamma rays to enhance drought resistance [2], while the kipas putih soybean was subjected to gamma radiation to promote early maturity and high-yield soybean mutant [3,4,5,6]. Additionally, the Detam 3 soybean variety was exposed to gamma rays to improve its tolerance to saline soils [7].…”

“…The M.1.1.3 line is a soybean line derived from gamma-ray irradiation of the Kipas Putih mutation. It has a shorter harvest age than its parent, but smaller seed size [5].…”

Effect of gamma irradiation on the germination, pollen viability, and morpho-agronomic of Pachyrhizus erosus cv. Kota Padang

“…Gamma-ray is the primary physical mutagen to induce favorable mutations at high frequency, depending on plant species (Denissen and Den Nijs 1987), varieties (Addai and Safo-Kantanka 2006;Tshilenge-Lukanda et al 2013;Muhammad et al 2021), and dose of irradiation (Ji-Min et al 2011;Tshilenge-Lukanda et al 2013;Harsanti et al 2020). Most mutant varieties released were developed using gamma irradiation (Ahloowalia et al 2004;IAEA Mutant Variety Database 2021;Nilahayati et al 2022).…”
