“…Traits controlled by additive gene action will have a high response to selection as the traits of interest and can be helpful as selection criteria for further improvement (Varona et al, 2018). Previous studies reported that pure line selection and mass selection were beneficial for traits managed by an additive gene action in the foxtail millet (Prasanna et al, 2013), while Meriaty et al (2021) used pedigree selection for such traits in soybean. Non-additive gene action governed the inheritance of three targeted traits in the foxtail millet breeding program, i.e., plant height, heading time, and grain weight per plant.…”

From a nutritional and health point of view, Foxtail millet (Setaria italica [L.] P. Beauv.) is one of the valuable millets due to its adaptability to adverse environmental conditions and ideal characteristics for functional genomics studies. Despite the increased number of studies on foxtail millet globally, however, presently in Indonesia, it is an underutilized crop species. Through conventional hybridization, combining superior traits has been conducted to produce high-yielding cultivars with early maturity and medium plant stature in foxtail millet. The pertinent study aimed to elucidate the genetic diversity in F 2 populations derived from the cross of Botok-10 × ICERI-5 and approximate the broad-sense heritability and gene actions controlling various traits in foxtail millet. The study's genetic material used 352 F 2 populations from the crossing of two potential parental genotypes of the foxtail millet: Botok-10 and ICERI-5. The results enunciated several individual F 2 populations with medium plant stature and earlier heading time compared with the parental genotypes. These potential F 2 segregants were also higher yielders than the male parent (ICERI-5). Non-additive gene action controlled the inheritance of the three targeted traits, i.e., plant height, heading time, and grain weight per plant in the foxtail millet. The heading time and grain weight per plant traits showed the highest genetic coefficient of variation (GCV) and moderate broad-sense heritability, and the plant height showed moderate GCV and low broad-sense heritability in the foxtail millet. All observed traits, except stem diameter, showed a significant positive correlation with grain weight per plant. The selection differential values indicated that the selected individuals have faster heading time and higher grain weight per plant than the overall F 2 populations.

“…In many plants, seed characters are used to select the best genotypes to breed. According to Meriaty et al (2021), the number of pods characterizes a rather high genetic advancement, suggesting that there is a good chance that these traits will be passed down to the following generation and that selecting soybean genotypes with numerous pods is quite simple.…”

“…Pedigree selection is based on individual performances from the best families (Arifiana and Sjamsijah, 2017). This selection can be started in the early generations and is generally always recorded during the selection process, so the lineage is known in detail (Meriaty et al, 2021). This selection method also can be used for gaining a high yield sorghum variety.…”

Importance of the work:The sorghum mutant "Gando Keta"is known to have a sticky texture but low production levels, with mutations expected to produce plants with improved yields. Objectives: To use gamma radiation to produce sorghum mutants of "Gando Keta" with high yield and fluffy texture. Materials & Methods: Explants (2 mm high, aged 3 d) were exposed to radiation doses in the range 10-100 Gy in 10 Gy increments. The shoots were acclimatized and their variability was observed. Then, 30 2 nd generation mutant (M2) plants for each dose of 40 Gy, 50 Gy, 60 Gy and 70 Gy were planted and observed for plant height, panicle diameter, panicle length, wet and dry panicle weights and seed weight. Results: Analysis of variance showed significant differences in mean plant height, stem diameter and panicle length. Radiation with doses of 40 Gy and 50 Gy produced significantly greater plant heights than those irradiated with a dose of 70 Gy. Observations on the growth characteristics of the six selected genotypes showed that the genotype "GK50-18" had a significantly greater plant height compared to M2, while the genotypes "GK60-13" and "GK70-5" were significantly lower than the M2 population. Seed weight had wide genetic variability and high heritability, so selection should be based on seed weight characters using the pedigree technique. Amylose analysis identified genotypes with lower amylose contents that should be further tested to determine the stability of the results. Main finding: Selection on the 2 nd generation mutant (M2) population obtained six genotypes with higher productivity: "GK50-18", "GK50-19", "GK60-11", "GK60-13", "GK60-9" and "GK70-5".
