programme should be based on the extent of
variability along with heritability and genetic
advance. Selection competence would be more
operative when we determine relationship between
various plant character and yield through correlation
coefficient analysis (Rekha and Celine, 2013). Path
coefficient analysis separates genotypic association
among variables into direct and indirect effect of
component characters towards yield (Nayak and
Nagre, 2013). Selection index commonly use in
conventional breeding as an important selection
criterion in order to reduce improvement complexity
of trait relationship and to gain economic yield
(Fotokian and Agahi, 2014).
Therefore, in the present study, an attempt has been
made to assess the trait efficiency in brinjal by genetic
variability, character association and selection index,
and select some promising genotypes through biplot
analysis.
