Abstract:
The experiment was conducted during the period from November 2011 to March
2012 at the research field of the Olericulture Division, Bangladesh Agricultural
Research Institute, Gazipur. A total of 5 parents (P

of capsicum were used in the experiment. The experiment was laid out in two
factors Randomized Complete Block Design with three replications. Mean
performance, variability, correlation matrix, combining ability and heterosis
analysis were done on yield and yield contributing characters, viz. days to 50%
flowering, plant height, individual fruit weight at green stage, individual fruit
weight at mature stage, number of fruits per plant, length of fruit, diameter of
fruit, fruit yield per plant at green stage, fruit yield per plant at mature stage, fruit
yield per hectare at green stage and fruit yield per hectare at mature stage.
Significant variation was recorded for yield contributing characters and yield of
capsicum. Fruit yield per plant at mature stage in terms of phenotypic variation
(11247.04) was higher than the genotypic variance (10315.43) with high
heritability (91.72%) for fruit yield per plant at mature stage attached with high
genetic advance (256.79%) and high genetic advance in percentage of mean
(43.04). Both additive and non-additive gene actions were important in governing
the yield and its attributing components. Hybrids P
