Abstract
The present investigation entitled, “Evaluation of capsicum [Capsicum annuum L. var.
grossum Sendt.] cultivars under field condition in the coastal zone of Odisha” was carried out
at the Experimental Farm, Department of Vegetable Science, OUAT, Bhubaneswar, Odisha
during rabi season of the year 2016-2017. Eight diverse cultivars were evaluated in a randomized
block design experiment with three replicates. Data were collected on days to 50% flowering,
plant height at 50% flowering, days to first harvest, plant height at last harvest, number of
branches per plant, leaf area, number of fruits per plant, fruit length, fruit girth, fruit weight,
number of lobes per fruit, number of pickings, harvest duration, total soluble solids, ascorbic acid
content and fruit yield (g/plant, kg/plot and t/ha). Mean values were used to determine characters’
phenotypic and genotypic coefficients of variation. Broad sense heritability and genetic advance
as percentage of mean was estimated for each trait. Direct and indirect effects of various traits on
fruit yield and inter-relationship among different traits were also studied. Analysis of variance
showed significant differences for all the traits. The genotype Kandaghat sel-1gave the highest
yield (16.23 t/ha) and performed better for other important horticultural traits over the check
cultivar California Wonder (14.85 t/ha). The cultivar Arka Mohini was earliest to come to first
harvest. Less difference between PCV and GCV was found for all traits except number of
branches per plant and number of pickings indicated less influence of environment on the
character thus the traits can be used for selection. High heritability coupled with moderate genetic
gain was obtained for fruit yield per plant (94.05% & 39.66%), fruit weight (95.74% & 33.74%),
plant height at last harvest (94.34% & 27.46%), harvest duration (89.36% & 35.87%) and quality
parameters indicating scope for their improvement through selection. Fruit yield per plant was
significantly and positively correlated with fruit weight, number of fruits per plant, fruit girth,
plant height at 50% flowering, leaf area, number of branches per plant and number of lobes per
plant. Maximum positive direct effect towards fruit yield per plant was contributed by fruit
weight and number of fruits per plant suggested that attention needs to be given on these
characters while designing crop improvement programmes in capsicum
