The present investigation on
genetic variability including mean, genotypic and phenotypic
variances, coefficient of variation, heritability, and
genetic advance was conducted on genetically diverse twenty
three genotypes of bell pepper. Significant differences were
observed among the genotypes for all the traits. On the
basis of mean performance, genotypes PRC-1, SSP, Kandaghat
Sel. and Ranichauri Sel-1 were outperformed for fruit yield
per plant, average fruit weight, number of fruits per plant
and took less number of days to 50% flowering. The
phenotypic coefficient of variation (PCV) and genotypic
coefficient of variation (GCV) were high for fruit yield per
plant and ascorbic acid content indicating that these traits
had wide genetic variability and would respond better to
selection. High heritability
and
high genetic advance were recorded for average fruit weight,
fruit yield per plant, fruit diameter, number of lobes per
fruit, days to first harvest, leaf area and ascorbic acid
content indicating the role of additive gene action for the
inheritance of these traits. At genotypic levels, the traits
fruit length, fruit diameter and number of fruits per plant
revealed significant positive correlation with fruit yield
per plant. Number of fruits per plant exhibited the highest
positive direct effect followed by average fruit weight,
number of branches per plant, pedicel length and harvest
duration at genotypic level.
