Relationships between Different Growth and Yield Traits in Bottle Guord [Lagenaria siceraria (mol.) Standl] with Path Coefficient Analysis over Seasons under Salt Affected Soil

Abstract

This study used 23 genotypes of bottle gourd—27 F1 hybrids, 12 Parents (9 lines, and 3 testers)—during two seasons (Y1 and Y2) and pooled analyses to analyze the correlations between fruit production per plant (Kg), growth, and economic features. The observations were evaluated based on qualities that are related to growth and yield. It was discovered that the fruit yield per plant had exhibited a significant and positive phenotypic correlation with the length of the male and female flowers' pedicels, the number of primary branches per plant, the length of the vine, the number of nodes per vine, the internodal length, the duration of picking, the length of the peduncle, the length of the fruit, the average fruit's circumference, the average fruit's weight, the number of fruits per plant. The 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
