DF = degrees of freedom, SS = sum of squares, MS = mean sum of squares (SS/DF).
a
Mean squares tests the significant effect of locations.
b
Tests the significant effect of overall least significant mean of the parents vs that of the progeny across sites and seasons.
c
Tests the significant effect of least significant means of individual genotypes (parents and progeny) across sites and seasons.
d
Tests the significant effect of site on overall parent and progeny least significant means.
e
Test the significant effect of genotype × environment interaction.
