Studies on Maize Yield under Drought Using Correlation and Path Coefficient Analysis

Correlation and Path Coefficient Analysis for ‘Yield Contributing’ Traits in Quality Protein Maize (Zea mays L.)

“…of kernel rows per ear (0.0029). Similar findings were reported earlier by [5,[10][11][12]17,19,21,[24][25][26].…”

“…Path coefficient analysis at genotypic level (Table 4) revealed that the highest positive direct effects on grain yield per plot was exhibited by Days to 75% tasseling (5.3447) followed by ear length (3.0313 [5,[10][11][12][17][18][19][20][21][22][23][24] for improving the grain yield of maize.…”

Correlation and Path Coefficient Analysis for Yield Contributing Traits and Grain Zinc Concentration in Biofortified Inbred Lines of Maize (Zea mays L.)

“…It had negative and non-significant correlation with grain yield (-0.0174P,-0.178 G).Cob diameter had positive and significant correlation with grain yield (0.2353P, 0.3299G) (Kumar et al, 2014) and negative and highly significant correlation with GZC (-0.3491P, -0.4741 G). Hundred seed weight showed positive and non-significant correlation with grain yield (0.0699P, 0.0859G) (Gazal et al, 2018) while negative and highly significant correlation with GZC (-0.2863 P, -0.3129 G). Days to 50% tasseling showed negative correlation with grain yield (-0.086 P and -0.330 G) and also significant and negative correlation with grain zinc concentration (GZC) (-0.2514P, -0.6421G).…”

“…It had positive and significant genotypic correlation with GZC (0.2335) and positive non-significant phenotypic correlation with GZC (0.159). Plant height had positive and non-significant correlation with grain yield (0.0267P, 0.0632G) (Gazal et al, 2018) and GZC (0.0417P, 0.0582G). Cob length without husk showed positive and non-significant correlation with GZC (0.0114P, 0.0373 G).…”

“…It had positive correlation with GZC (0.0439P, 0.0549G). Ear height showed positive correlation with grain yield (0.1039 P, 0.156G) (Kumar et al, 2006;Jawaharlal et al, 2011;Barua et al, 2017;Gazal et al, 2018). It had positive and significant genotypic correlation with GZC (0.2335) and positive non-significant phenotypic correlation with GZC (0.159).…”
