Fig. 4From: High-throughput phenotyping allows the selection of soybean genotypes for earliness and high grain yieldPath diagram for results from Tables 6 and 7 for dependent variables (grain yield—YIE and days to maturity—DM) as function of selected vegetation indices (NDVI, NDRE and GNDVI). Dashed lines indicate Pearson’s correlations between variables, while continuous lines reveal the direct effects obtained by path analysis (previously performed)Back to article page
