Genetic variability, character association and path coefficient studies were carried out for yield and yield contributing
characters for twenty-four diverse genotype of pea. The results revealed a wide range of phenotypic variation, along with
high heritability in pea. Highest pod yield per plant was recorded in VRP-229 followed by VRP-372 and VRP-305. The
characters namely, plant height and weight of seeds per pod showed high magnitude, while number of pods per plant,
number of branches per plant and pod yield per plant showed moderate magnitude for phenotypic and genotypic coefficient
of variation. The heritability and genetic advance were high for days to first pod initiation, plant height and pod yield per
plant indicating its additive gene action for their expression. Character association studies revealed that pod yield per
plant exhibit positive and highly significant correlation with number of pods per plant, number of branches per plant and
days to fifty percent flowering. The path coefficient studies also revealed that maximum positive direct effect was observed
through number of pods per plant followed by days to first flowering, single pod weight and pod length towards yield
indicated that these characters may be considered as the most reliable selection indices while making selection for high
yielding genotypes.
