Bottle gourd (Lagenaria siceraria), one of the oldest crop of tropics and one of the least calorie vegetable, providing just 14 calories per 100 g is attaining fast popularity among the health conscious urban elite. In vegetable breeding programmes the co-relation coefficient analysis have been used frequently in order to know the mutual relationship between variables, affecting the target variables and the finding and guide for component variable on which selection should be based for future improvement. Simple correlation gives information about inheritance of two characters and identifies the characters needed for improvement of the target parameters. It reveals both the strength as well as nature of relationship between two characters. Significance of correlation value means the association between two characters is high. Negative co-relation means the increase in one variable will lead to decrease in other variable. When value of genotypic Yield is a complex character controlled by a large number of contributing characters and their interactions. For any effective selection programme, it would be desirable to consider the relative magnitude of association of various characters with yield. The path coefficient technique helps in estimating direct and indirect contribution of various components in building up the total correlation towards yield. The present study was conducted with 10 lines and bottle gourd genotypes including one check variety i.e. Kanak, sown in Randomized Block Design (RBD) with three replications in rainy season-2015 to assess the nature and magnitude of association among yield and its contributing traits in bottle gourd at Vegetable Research Farm of the Department of Horticulture, Institute of Agricultural Sciences, BHU, Varanasi. A highly significant and positive genotypic correlation was observed for number of fruits per plant with fruit yield per plant (kg) and fruit weight (kg) while this character had highly significant negative association with fruit girth (cm). Path coefficient analysis revealed that average fruit weight had the highest positive direct effect on fruit yield followed by number of fruits per plant, fruit girth (cm), days to 50% male flowering, fruit length (cm), days to 50% female flowering and number of primary branches per vine.
