Soybean Agronomy Character Selection (Glycine Max [L.] Merril) in F3 Offspring through Organic Breeding

Introduction

The world's population is projected to reach 9.7 billion by 2050, putting immense pressure on the global food system to produce more food with limited resources. Soybean (Glycine max [L.] Merril) is one of the most widely cultivated legumes, providing a rich source of protein and oil for human consumption and animal feed. However, soybean yields are often limited by environmental factors, such as soil conditions, weather, and pests, making breeding for improved agronomic characters essential. This study aims to investigate the selection of soybean agronomy characters in F3 offspring through organic breeding, with a focus on seed weight and number of pods.

Background and Significance

Soybean breeding has been a crucial component of agricultural research, aiming to improve crop yields, disease resistance, and environmental sustainability. Organic breeding, in particular, has gained attention in recent years due to its potential to promote sustainable agriculture and reduce the environmental impact of conventional farming practices. The selection of agronomic characters, such as seed weight and number of pods, is a critical step in plant breeding, as it determines the final outcome and quality of the product produced. This study contributes to the existing body of knowledge on soybean breeding by exploring the effectiveness of organic breeding methods in selecting superior agronomic characters.

Selection Methodology and Parameters

In this study, individual selection was based on observed parameters, such as seed weight and number of pods, with a selection intensity level of 20%. The characters chosen in the F3 generation were seed weight and the number of pods, which are considered representative for selection activities and are expected to produce superior individuals in the next population. The selection process was conducted on Jalan Pasar 1 No. 296, TJ Sari, Medan Selayang, with two different cultivation methods, namely organic and non-organic cultivation. The results of this study will provide valuable insights into the selection of agronomic characters in soybean breeding, especially in the context of organic breeding.

Analysis of Research Results

The results of this study show varied results, with heritability that is relatively moderate to low. This is caused by a large enough environmental variation that affects the growth and development of soybean plants. Environmental variation can come from various factors, such as soil conditions, weather, and aquaculture practices that are applied. This study highlights the importance of considering environmental factors in plant breeding, as they can significantly impact the final outcome and quality of the product produced.

Discussion and Implications

This study provides valuable insights into the selection of agronomic characters in soybean breeding, especially in the context of organic breeding. By implementing measurable character-based selection, it is expected that farmers can produce more productive and quality soybean varieties. The results of this study can be a reference for the development of superior soybeans that can support food security and increase farmers' income. In facing future agricultural challenges, the application of sustainable breeding methods and based on in-depth research will be the key to creating agricultural products that are not only efficient but also environmentally friendly.

Conclusion and Future Directions

This study demonstrates the effectiveness of organic breeding methods in selecting superior agronomic characters in soybean breeding. The results of this study provide valuable insights into the selection of agronomic characters in soybean breeding, especially in the context of organic breeding. Future studies should focus on exploring the application of sustainable breeding methods and based on in-depth research to create agricultural products that are not only efficient but also environmentally friendly. Additionally, further research is needed to investigate the impact of environmental factors on soybean yields and to develop more effective breeding strategies for improving crop yields and disease resistance.
