The material for the present study consisted of 30 F4 families of bhendi, to assess the genetic components for growth and yield at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, UT of Puducherry, India. The mean values and ranges recorded for various traits under study revealed significant variation. The maximum range of variability was observed for fruit yield plant-1 (148.0 to 377.31 g), followed by plant height at final harvest (76.56 to 160.40 cm). The phenotypic coefficient of variation was found higher than genotypic coefficient of variation for all the traits. The highest value of genotypic coefficient of variation was observed for fruit yield plant-1 (20.48 per cent) and number of fruits plant-1 (20.204 per cent). The maximum value for phenotypic coefficient of variation was recorded for fruit yield plant-1 (29.824 per cent), followed by number of fruits plant-1 (28.952 per cent) and plant height at final harvest (27.202 per cent). The heritability in broad sense was found to range from 0.503 per cent (first flowering node) to 48.699 per cent (number of fruits plant-1). Number of fruits plant-1, fruit yield plant-1, plant height at final harvest, fruit length, plant height at flowering, days to first flowering and fruit girth recorded moderate heritability and rest of the characters recorded low heritability. None of the characters studied recorded high or moderate magnitude of genetic advance as per cent of mean.
