Abstract:
A field experiment was conducted during March to July, 2022 to determine correlation coefficient and path analysis among 28 genotypes for 18 characters comprised of fruit yield and its contributing characters. These genotypes were planted in Randomized Block Design with three replications at Vegetable Research Centre, G. B. Pant University of Agriculture & Technology, Pantnagar. The result revealed that at genotypic and phenotypic level maximum significant and positive correlation was shown by fruit weight (cm), fruit length (cm), fruit diameter (cm), total number of pickings and number of seeds per fruit. The results of path coefficient analysis indicated that at phenotypic and genotypic level, the effect was significant and positive direct effect on fruit yield per plant (kg) was contributed by the character fruit weight (g) followed by number of fruits per plant, days to first male flower, number of pickings, fruit diameter (cm), days to first fruit harvest, main vine length (m), number of seeds per fruit, sex ratio, days to first female flower, node number at which first female flower appears and number of nodes per vine. Hence, these characters may be simultaneously selected for developing better quality high yielding varieties of bitter gourd.
