the genetic parameters, phenotypic coefficient of
variation (PCV), genotypic coefficient of varia-
tion (GCV), broad sense heritability, and co-

So as to get the path coefficients at the geno-
typic and phenotypic levels, one needs to have the
correlation coefficients at the genotypic and phe-
notypic levels. The genotypic and phenotypic
correlations could be obtained by partitioning the
sum of squares and products due to the treatments
into genotypic and phenotypic components.
We demonstrate the whole process in a step-
wise manner as provided in Sahu and Das (2009)
Step 1: Analysis of Variance for the Characters
Under Study
The analysis of variance for all the characters
is taken up one by one. In the following steps, we
demonstrate the analysis of variance procedure
for a single character, that is, leaf yield per plant
in details, and only the results of the analysis of
variance for
the rest of
the characters are
presented.
