Abstract

This study aims to explore the relationship between several traits among 18 ridge gourd hybrids. It was carried out during the rabi season of 2021–2022, at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, U.T. of Puducherry. Twenty yield-related qualities were assessed using a randomized block design with two replications in order to determine the associations among various characters. The yield per vine was found to have a highly significant and positive correlation with the following variables: vine length at final harvest, number of primary branches vine-1, number of female flowers vine-1, days to final harvest, fruit length, fruit girth, number of seeds fruit-1, total number of harvest, number of fruits vine-1 and weight of individual fruit. Path analysis revealed that the characters such as number of female flowers vine-1, days to first female flower anthesis, total number of harvest, sex ratio, total soluble solids, days to first male flower anthesis, vine length at final harvest, number of seeds fruit-1, days to first harvest, number of primary branches vine-1, fruit length, fruit girth, number of seeds fruit-1, number of fruits vine-1 and weight of individual fruit are considered as important traits which directly and indirectly influences towards yield. It implies that the characters strongly influence the yield vine-1 and hence selection for these traits would be considered important in selection of hybrids for yield.
