Abstract:
The present experiment was undertaken with the objective to estimate nature of variation and associations among different horticultural traits. Ten parthenocarpic hybrids were raised in Randomised Block Design replicated thrice and data were recorded on marketable yield and its related traits. The results showed that Phenotypic Coefficient of Variation and Genotypic Coefficient of Variation estimates were high to moderate for vine length and number of female flowers per node. High heritability along with high genetic advance was recorded for internodal length, vine length, number of female flowers per node and total soluble solids. Genotypic correlation was higher than phenotypic correlation indicating highly heritable nature of these characters. The path coefficient analysis revealed that the number of fruits per plant, fruit weight, days taken to first fruit harvest and nodal position of first female flower had direct positive phenotypic and genotypic effect on the yield. Therefore, direct selection on the basis of number of fruits per plant and fruit weight will be rewarding for crop improvement in parthenocarpic cucumber.
