Graph of the variables and individuals of the principal component analysis. NLP Number of leaves per plant, SWP Seeds weight per plant (g), TSW Thousand seed weight (g), NIP Number of inflorescences per plant, NTB Number of total branches, SD Stem diameter (cm), DMY Dry matter yield (T/ha), CF Crude fiber (% DM), NDF Neutral detergent fibers (% DM), ADF Acid detergent fibers (% DM), ADL Acid detergent lignin (% DM), IVEOMD Enzymatic organic matter digestibility (%), NFE Nitrogen-free extract (% DM), ME metabolizable energy (MJ/kg DM), Hum. Humidity (%), FnSilt Fine silt (%), P Available phosphorus (ppm), EC Electrical conductivity (mS/m), OM Organic matter (%), BIO6 Min temperature of coldest month (°C), BIO12 Annual precipitation (mm), BIO13 Precipitation of wettest month (mm), BIO14 Precipitation of driest month (mm), BIO16 Precipitation of wettest quarter (mm), BIO17 Precipitation of driest quarter (mm), BIO18 Precipitation of warmest quarter (mm), BIO19 Precipitation of coldest quarter (mm). Four clusters were determined by the cluster heatmap analysis and represented via the four colored circles (green, purple, yellow, and blue) on this figure.
