The researchers evaluated different types of giant miscanthus plants to see which ones could produce the most bioethanol. They found that two specific lines, 108 and 202, were the most productive, with potential bioethanol yields higher than the control line by 10.7% and 14.2% respectively. These lines could compete with other plants for making bioethanol in Ukraine. However, sweet sorghum is still more productive when used for both first- and second-generation bioethanol.
