“…The R cross had individuals with many extreme branches, reaching up to 17 branches as indicated by G252. In this study, the average number of branches per plant was 5.6, which was higher than the study by Badiaraja et al (2021a,b) and Mustofa et al (2021), who reported an average number of branches of 2.1-3.85. Crosses with the most reproductive nodes per plant were obtained in the M cross (Figure 2C).…”

Abstract. Zubaidah S, Kuswantoro H, Uge E, Rozana K, Purwantoro. 2023. Characteristics contribution and similarity of F5 soybean lines resistant to cowpea mild mottle virus derived from different crossing. Biodiversitas 24: 5399-5408. Virus is one of the pathogens that can infect soybeans. One of the crucial viruses is Cowpea Mild Mottle Virus (CpMMV), which attacks many soybean plants in Indonesia. The objective of this study was to explore the character's contribution and similarity to identify F5 CpMMV-resistant soybean lines. The plant materials were F5 CpMMV-resistant soybean lines from 26 different crosses. CpMMV inoculation was performed naturally by placing the experiment at the site previously infected with Bemisia tabaci as the CpMMV virus vector. Observations were made on agronomic characters and disease scores. The results showed that there was a variation in the observed agronomic characters, but disease scores were generally at a score of 2. Seed yield, number of filled pods, and number of seeds showed strong character contributions. Disease scores generally had the opposite direction to seed size. There was a significant correlation between agronomic characters, but disease scores had no correlation with agronomic characters. M and N crosses showed the highest seed yields. The disease score for these two crosses was 2. These two crosses also formed a separate group. There were four groups of crosses with different numbers of members. The groups formed were more influenced by the variability of the number of seeds, filled pods, and plant height. Based on seed yield and disease score, M and N crosses should be further developed to obtain high-yielding CpMMV-resistant soybean varieties.

“…Machado et al [34] reported a negative genotypic direct effect on total pod number toward seed yield. Mustofa et al [35] showed a significant direct effect on 100-seed weight and productive nodes, as well as indirect effect on productive nodes through filled pods, and pods number through 100-seed weight and productive nodes. Malek et al [10] suggested strong associations and large direct effects as the basis for seed yield selection.…”

Genetic variability and relationship among characters plays important roles in development of plants varieties. The aim of the research was to study genetic variability and relationship among characters. Fifty soybean lines were grown in randomized complete block design with three replicates. The number of branches and seed yield that had broad genetic variability. The maturity, branches, and 100-seed weight had high heritability. Seed weight per plant and seed yield showed significant genotypic correlations. The phenotypic correlation among characters was found between seed yield with number of filled pods, 100 seeds weight and seed weight per plant, branches with productive node and filled pods, and productive nodes with filled pods. Phenotypic path coefficient revealed that flowering, branches, 100-seed weight, and seed weight per plant contributed directly to seed yield per plot. Despite having high heritability and broad genetic variability, branches per plant showed negative indirect effect through number of nodes and seed weight per plant, while seed weight per plant showed positive indirect effect through number of branches per plant. Direct selection should be based on seed yield, while indirect selection should be based on seed weight per plant.

“…The said differences could have impacts gained from the genetic makeup of the genotypes and environmental conditions, such as, water availability and soil acidity (Pregitzer et al, 2013). According to Mustofa et al (2020), the trait seed yield is the chief attribute that becomes the selection criteria for high-yielding soybean genotypes. Both female and male parents contribute some of the genes to their offspring; however, the influence of the female parent often extends beyond simple genetic transmission (Munganyinka et al, 2015).…”

“…Genetic diversity provides plant breeders to develop new and improved cultivars with desirable characteristics, including farmer-preferred traits with yield potential and large seeds. Genetic diversity facilitates breeders to develop cultivars for specific features like quality improvement and tolerance to biotic and abiotic stresses (Bhartiya et al, 2012;Bhandari et al, 2017;Mustofa et al, 2020). One of the efforts to increase soybean production is creating new variants through artificial crosses involving various superior parental genotypes.…”

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.
