Identification and Genetic Characterization of the Glycine Max L. Merril) Generation M5 Based on the Content of Fatty Acids using Simple Sequence Repeats (SSR) Markers

Introduction

Soybeans (Glycine max L. Merril) are one of the most widely cultivated legumes in the world, and their importance in food, feed, and industrial applications cannot be overstated. The nutritional value of soybeans is largely attributed to their high content of protein and fatty acids. However, the quality and quantity of fatty acids in soybeans can vary significantly depending on factors such as genetic diversity, environmental conditions, and breeding practices. In this study, we aimed to reveal the genetic diversity of soybean mutant lines based on fatty acid content using Simple Sequence Repeats (SSR) markers.

Materials and Methods

The research was conducted at the Molecular Genetic Laboratory, Faculty of Agriculture, University of North Sumatra, Medan. A total of 12 soybean mutant lines, 1 elder, and 1 comparison variety were analyzed. The research team used four SSR primers, namely GMFAD2 1A/B, GMFAD2 1A/2B, GMFAD2A/1B, and GMFAD2 2A/B. The PCR reactions were performed using a thermocycler, and the amplified products were separated using gel electrophoresis. The sizes of the amplified fragments were determined using the Uvitec Cambridge FireReader software.

Results

The results of the study showed that only the primary GMFAD2 1A/2B primer was polymorphic, with fragment sizes ranging from 60-146 bp. The analysis of PCOA (Principal Coordinate Analysis) identified 3 different soybean mutant lines, namely M5 (200) -A-11-39-7, M5 (100) -A-25-2-7, and M5 (100) -A -25-3-7. The genetic similarity analysis using the Multivariate Statistical Package software (MVSP VER. 3.2) showed that 14 individuals were divided into 2 main groups, with genetic equality values ranging from 0.24-1.

Discussion

The results of this study have important implications in the development of soybean varieties with better quality fatty acid quality. Identification of different mutant lines based on fatty acid content can be the basis for soybean selection and breeding. The genetic diversity revealed in this study can be used to develop new soybean varieties with improved fatty acid profiles, which can enhance the nutritional value and health of soybean processed products.

Meaning and Implications

The development of soybean varieties with better fatty acid content is very important to increase the nutritional value and health of soybean processed products, as well as increasing the competitiveness of Indonesian soybean products in the global market. The results of this study can be used to develop new soybean varieties with improved fatty acid profiles, which can enhance the nutritional value and health of soybean processed products.

Further Analysis

This research can be continued with further analysis, such as:

Characterization of Fatty Acids

Complete analysis of fatty acid compositions in the mutant strain identified to uncover significant differences on the fatty acid profile.

Field Trials

Evaluation of the performance of the mutant strain in the field to see the effect of genetic diversity on yields and resistance to pests and diseases.

Genetic Study

Development of specific SSR markers that are specific to genes that control the synthesis of fatty acids in soybeans, to get a deeper understanding of the genetic mechanisms involved in the variation of fatty acid content.

Conclusion

In conclusion, this study revealed the genetic diversity of soybean mutant lines based on fatty acid content using SSR markers. The results of this study have important implications in the development of soybean varieties with better quality fatty acid quality. The genetic diversity revealed in this study can be used to develop new soybean varieties with improved fatty acid profiles, which can enhance the nutritional value and health of soybean processed products.
