Inter-correlation and path co-efficient analysis for agro-morphological and yield traits in bottle gourd (Lagenaria siceraria)
Year: 2025
Type: article
Abstract: The study was carried on Inter-correlation and path co-efficient analysis of bottle gourd (Lagenaria siceraria) at Vegetable Research Farm, RLBCAU, Jhansi, Uttar Pradesh during kharif 2022. A total of 30 genotypes were sown in a randomized block design with three replications. Observations were recorded on 15 characters. Higher magnitude of GCV and PCV was recorded for fruit length (cm), fruit width (cm) and yield/plant (Kg/plant). The insignificant difference between GCV and PCV was recorded for most of the traits indicated that traits were less impacted by the environment. The inter-character association at phenotypic and genotypic correlation coefficients suggested that yield/plant recorded highly positive significant correlation with fruit width, average fruit weight and number of fruits/plant at both genotypic and phenotypic levels. Path coefficient analysis revealed highly positive direct contribution towards yield/plant with number of fruits/plant, fruit width and average fruit weight at both genotypic and phenotypic level. On the other hand, vine length, days to first flowering bud, days to first fruit setting, days to first fruit picking and fruit length showed negative direct effect on fruit yield/pant.
