 ABSTRACT

The objectives of the present study were to evaluate the associations between yield and yield contributing traits and identify the direct and indirect effects of component traits on fruit yield of ash gourd to enable selection of promising lines. Observations were recorded for two seasons (rainy seasons of 2015 and 2016) on 18 ash gourd genotypes (local landraces and released varieties). Correlation coefficients indicated that yield per vine had significant and positive association with number of branches per vine (0.318,0.137) , number of female flowers per vine (0.078, 0.565) , sex ratio (0.579, 0.322), fruit length (0.604, 0.463), fruit diameter (0.743, 0.565), average fruit weight (0.830, 0.758), number of seeds per fruit(0.387,0.286) , weight of seeds per fruit (0.635, 0.478) and vine length (0.395, 0.340). Negative associations were noticed with node to 1st female flower (-0.279, -0.280) and days to 1st fruit setting (-0.465, -0.189). Number of fruits per vine (0.108) was positively associated with yield per vine at phenotypic level only. Path coefficient analysis revealed that number of female flowers per vine (6.221), vine length (5.727), fruit diameter (5.201), fruit length (0.647), days to 1st fruit setting (3.455), number of branches per vine (1.300) and weight of seeds per fruit (0.892) directly contributed to the yield of ash gourd.
