“…According to Yang et al (2009), at least 60% of the data variation must be explained by the first two PCs. Similar values for total variation detected by PCs were reported by Gravina et al (2020), who evaluated morpho-agronomic traits in elephant grass genotypes and described that 70.07% of the total variation was explained in the first two PCs.…”

“…The high coefficients of variation (CV) obtained for DMY (37.53%), NT (30.51%), and SD (21.40%) are acceptable, considering that the traits evaluated in this study are quantitative and, consequently, highly influenced by the environment. Gravina et al (2020) and Souza et al (2017) also worked with elephant grass and found similar results regarding CV in experiments evaluating the same quantitative traits.…”

“…The coefficient of variation (CV) for DMY, DM content (%DM) and plant height (HEI) traits found were, respectively, 39.05%, 10.01% and 9.90%, at the first year of cultivation, and 31.47%, 13.22% and 6.64%, at the second year of cultivation (Table 1). While some values of the coefficients of variation are classified as very high, these results support the results normally found in studies with culture under field conditions (Rossi et al, 2014;Oliveira et al, 2014;Rocha et al, 2015;Gravina et al, 2020).…”

“…https://doi.org/10.1590/ 1678-4499.20230198 Elephant grass [Cenchrus purpureus (Schumach.) Morrone] is an energy crop that has been widely studied due to its great potential for dry matter production, with high energy quality (Rocha et al 2015, Stida et al 2018, Silva et al 2020, Gravina et al 2020) and tolerance to unfavorable weather conditions such as water deficit (Habte et al 2022). Since 2007, the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) has been developing the elephant grass breeding program, which has driven the improvement of the crop and contributed to promoting its use in the northern region of the state of Rio de Janeiro, Brazil.…”
