“…Seed character and productivity are the target characteristics in food plant breeding programs. As is the case with sorghum plants, in soybean plants, the number of filled pods can be used as a character for selection (Lestari et al, 2022). In the current study, seed weight (one of the seed characters) was used to select desirable sorghum genotypes.…”

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".

“…Soybean is mostly an economically valuable dicot group plant globally because of its high protein and oil content. It provides vegetable protein for millions of people and ingredients for hundreds of chemical products (Rezyawati et al, 2018;Sulastri et al, 2020;Lestari et al, 2022). Soybeans contain significant amounts of phytic acid, dietary minerals, and B vitamins.…”

A three-way cross is an artificial cross performed to assemble superior cultivars for increased soybean production. The presented study aims to evaluate the percentage of success in the single cross and three-way cross of soybean genotypes to enhance the genetic variability in the base population of the genetic material. The genetic material comprises three soybean cultivars, i.e., Grobogan, Anjasmoro, and Dega-1. The three-way cross design operation made various crosses. Parameters observed were plant morphology, percentage of cross success and seed formation in pods, number of seeds in pod, and the total seed weight. The results showed a relatively high (57.14%) success rate for the cross Grobogan × Anjasmoro, producing numerous one-seeded and two-seeded pods and 30 seeds per plant with a total weight of 5.4 g. However, the success rate in three-way cross (F1 descent [Grobogan × Anjasmoro] × Dega-1) was medium (35.37%). The results of crossing the three genotypes of parents will greatly determine soybean variability.

“…The highest demand for soybean is due to the following: 1) soybean seed is a richer source of protein; 2) it fulfills the protein requirements in countries with economically inaccessible meat and dairy products, making soy a unique product; and 3) soybean cultivation helps solve the food and feed protein deficiency issues (Wijewardana et al, 2019). Soybean is a moderately salt-tolerant crop, and soil salinity is a chief limitation to their production in many regions worldwide (Ilangumaran et al, 2021;Lestari et al, 2022). Crop exposure to salt stress results in slower growth, increased leaf chlorosis, decreased biomass accumulation and protein content, and inhibiting the formation of nodules and nitrogen fixation, which eventually causes a significant decrease in crop yield (Adsul et al, 2016;Otie et al, 2021).…”

Soybean (Glycine max [L.] Merr.) is an economically important oilseed crop with an annual increase in growing grain demand. Soybean is a moderately salt-tolerant crop; however, salt stress conditions can affect its growth and yield-related traits and, eventually, reduce productivity. In saline soils, one of the techniques to increase soybean productivity is to use rhizobia inoculation. Although, using industrial rhizobia-based biofertilizers is often ineffective due to their lack of adaptability to salinity. Injecting soybeans with salt-tolerant and growth-promoting rhizobia helps mitigate the effects of salt stress harmful to crop plants. The recent study sought to isolate local strains of salt-tolerant rhizobia, studying its ability to increase soybean tolerance to salt stress conditions. Twenty-four local salttolerant rhizobium isolates underwent isolation from root nodules of soybean grown on saline soils. Studying their basic morphological and biochemical characteristics and ability to withstand salt stress led to the final selection of five salt-tolerant strains. The rhizobium strains were able to synthesize metabolites that stimulate growth and help reduce salt stress in plants. The study of rhizobia nodulation ability under saline conditions resulted in selecting the three most efficient strains from the Bradyrhizobium japonicum species. Inoculation of soybean seeds with salt-tolerant rhizobia proved to mitigate the adverse effects of salinity on plant growth by increasing the root size and the number of nodules in the roots. Thus, the study establishes that inoculation of soybean seeds with local salttolerant rhizobia enhances soybean tolerance to salt stress and improves crop growth and adaptation to soil salinity. Using isolated local strains of salt-tolerant rhizobia will help provide a key and environmentally friendly approach to solving the problem of salt stress for sustainable agriculture.
