The study evaluated 30 different types of sugar cane to see how well they grew and produced sugar in three different crop cycles. The researchers found that the sugar cane types varied in their ability to regrow after being harvested, with some types performing better than others. They also discovered that certain traits, like stalk weight and density, were higher in the initial crop cycle compared to subsequent ones. Overall, the study showed that some sugar cane genotypes have better yield potential and regrowth ability than others, which could help improve sugar production in the future.
