SURVEY OF GMO SOYBEANS IN TIEN GIANG PROVINCE AND COMPARISON OF PROTEIN AND LIPID CONTENT WITH NON-GMO SOYBEANS

Tóm tắt

The objective of this study is to determine the presence of genetically modified (GMO) soybean varieties in markets within Tien Giang province, and to compare the total protein and lipid content of these GMO soybeans with non-GMO soybean varieties. Twenty-one soybean varieties collected from various markets in Tien Giang province were subjected to genetic analysis. PCR was employed using specific primers targeting the 35S promoter and nos terminator sequences to detect the presence of genetically modified traits. Results showed that 52.38% of the 21 soybean varieties tested were genetically modified organisms (GMOs). The mean growth duration of these soybean cultivars was relatively short, approximately 61 days. A strong positive correlation was observed between plant height and node number. The soybean variety with the highest protein content is CG1 (0.67 %). The variety with the lowest lipid content is TP3 (8.71%).
