Abstract:
The experiment was conducted in Randomized Block Design with three replications to evaluate thirty morphologically distinct bottle gourd genotypes at the Main Experiment Station, Department of Vegetable Science at the Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.) during summer season of 2018. Fruit yield/ plant (kg) exhibited highly significant and positive correlation with number of fruits/ plant, node number to first staminate flowers, average fruit wt /fruit (Kg), node number to first pistillate flower and fruit circumference (cm). Whereas, significant but negative correlation was found with days to first staminate flower anthesis and days to first pistillate flower anthesis. Positive and non-significant correlation was recorded with fruit length (cm), days of first fruit harvest, number of primary branches per plant and vine length (m) at both genotypic and phenotypic correlation. The genotypic correlations were larger in magnitude than the corresponding phenotypic values, suggesting therefore a strong inherent relationship in different pairs of characters. Path coefficient analysis highest positive direct effect on fruit yield per plant was exerted by average fruit weight per fruit followed by fruits per plant, days to first fruit harvest, number of primary branches per plant, days to first staminate flower anthesis, node number to first staminate flowers and node number to first pistillate flower. While highest negative direct effect on fruit yield per plant was exerted by days to first pistillate flower anthesis followed by vine length (m), fruit length and fruit circumference.
