How to distinguish transgenic corn, hybrid corn and old variety corn

Directly hand over the purchased corn to the quality inspection department for the most inspection.

2. Intuitive identification method

1, fruit corn: corn that tastes sweet.

2. Golden millet corn: corn with similar grain size and golden color.

3. Colored corn: Millet has purple, white and Huang San colors, and it is a common transgenic corn.

Genetically modified corn: sweet, crisp, full and elegant, with similar head and tail.

transgenic technology

The theoretical basis of transgenic technology comes from molecular biology derived from evolution. The source of gene fragment can be the target gene needed to extract the genome of a specific organism, or it can be a synthetic DNA fragment with a specific sequence. DNA fragments are transferred into specific organisms, recombined with their own genomes, and then generations are artificially selected from the recombinants, so as to obtain individuals with stable performance of specific genetic traits. This technology can increase the expected new characters of recombinant organisms and cultivate new varieties.

hybridization technique

Definition: base pairing of two single-stranded DNA or RNA. Classical and commonly used experimental methods in genetics. A method for obtaining individuals whose parents are genetically recombined by mating between individuals with different genotypes. Generally speaking, the process of achieving this goal through the mutual fusion of germ cells is called hybridization; The process of achieving this result by somatic cell fusion is called somatic hybridization.
