“…Similarly, a dwarf mutant with a short internode length, named Dw607, was induced from variety Yuzhi 11 by EMS mutagenesis, and the internode lengths of the mutant plants decreased from 6.0 to 8.4 to 3.5–4.0 cm [ 10 ]. This result is in contradiction to the work of Birara et al [ 43 ] who studied mutation breeding using NaN 3 on quantitative traits of sesame, and their findings reported that there was no significant difference observed in internode length of various concentrations of mutagen treatments including the control.…”

“…Besides, the plant height of dw607 ( dwf1 ) significantly declined from 176.00 to 118.25 cm [ 42 ]. A similar study was conducted using sodium azide on quantitative traits of sesame [ 43 ]. Their findings reported that the maximum plant height at maturity was 66 cm while the minimum plant height was 55 cm at 0.02% and 0.05% sodium azide concentration, respectively.…”

The emerging oilseed crop Sesamum indicum, also known as the queen of oilseeds, is being grown globally for its oil content for medicinal and nutritional values. One of the key challenges of sesame cultivation is its low productivity. In the present study, sodium azide (NaN3) was used as a chemical mutagen. The aim of this study was to examine the effect of NaN3 on quantitative and qualitative stem traits in the M2 generation of Ethiopian sesame (Sesamum indicum L.) genotypes. Seeds of fourteen sesame genotypes were used in this study and germinated and grown under greenhouse conditions. Different qualitative and quantitative data were collected and analyzed. Traits such as plant height, ground distance to first distance, and internode length were significantly affected by NaN3 treatment. The highest plant height was recorded in the control on Humera 1 and Baha Necho genotypes, while the lowest was observed on Setit 2 and Hirhir treated with the chemical. The highest ground distance to the first branch was observed in Gumero, while the least ground distance was recorded in Setit 1 in the treated and control genotypes, respectively. The best internode length was recorded on Setit 2 and ADI in the control, while the lowest internode length was observed in Setit 1 genotype treated with sodium azide. Genotypes such as ACC44, ADI, Baha Necho, Borkena, Gonder 1, and Setit 1 treated with NaN3 have showed glabrous type of stem hairiness. All the fourteen genotypes (both treated and control) were clustered into four groups. In conclusion, we observed a highly significant variation among the genotypes due the effect of the chemical and genotypes themselves. Hence, this report would create more genetic diversity for further sesame genetic research improvements.
