Abstract
The objective of this study was to determine the relationships among fruit yield per plant (Kg), growth and economic traits using twenty three genotypes [27 F1 hybrids and 12 Parents (9 lines and 3 testers)] of bottle gourd during two seasons (Y1 and Y2) 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 length of pedicel of male flower, length of pedicel of female flower, primary branches per plant, vine length, number of node per vine, internodal length, picking duration, peduncle length, fruit length, average fruit circumference, average fruit weight, number of fruit per plant, fruit yield per plant, total soluble solids, reducing sugars, non- reducing sugar, total sugars and dry matter and negative significant association with days to first male flower anthesis, days to first female flower anthesis, node number to first male flower appearance, node number to first female flower appearance and days to first harvest at phenotypic level during two seasons and over seasons (pooled). 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. The soil type of experimental site was sandy loam with average fertility level and pH in the range of 7.5-8.5.
