The objective of this study was to determine the relationships among fruit yield per plant (Kg), growth and economic traits using twenty one genotypes (15 F1 hybrids and 6 Parents) of pumpkin during three seasons (E1, E2, E3) and pooled analysis worked out. The observations were measured on growth and yield attributing traits. The present investigation revealed that the fruit yield per plant had exhibited significant and positive phenotypic correlation with number of fruits per plant, average fruit weight, total soluble solids, vine length, flesh thickness, number of primary branches per plant, equatorial circumference of fruit and negative significant association with days to first male flower anthesis, days to first female flower anthesis, days to first fruit harvest, inter nodal length and node number to first male flower appearance at phenotypic level during all three seasons and over seasons (pooled) except node number to first male flower appearance during E1 and E2. Analysis of path coefficient revealed that highest positive direct effect on fruit yield per plant was exerted by number of fruit per plant followed by average fruit weight at phenotypic level. Whereas, higher negative direct effects exerted by days to first fruit harvest.
