How genetic seed improvement works
Web4 nov. 2024 · In field tests across corn-growing regions of the United States between 2014 and 2024, they found that the GM hybrids typically yielded 3% to 5% more grain than control plants. Some yielded 8% to 10% more, the team reports this week in the Proceedings of the National Academy of Sciences. The benefit held regardless of how good or bad the ...

WebGenetically modified seeds are created when one or two genes with the desired traits from any living organism are transferred directly into the plant’s genome. Higher yields are achieved when seed heads produce more seeds per head or bigger seeds; but plants with tall stalks cannot always support the added weight.
