Abstract:
The present investigation was carried out with the aim to know the association among the quantitative and qualitative traits and effect and intensity of these traits on the fruit yield of the pumpkin. Present study was conducted during Zaid, 2020 (Y₁) and Zaid, 2021 (Y₂). The present investigated shows that the most important trait fruit yield per plant had exhibited significant and positive phenotypic correlation with number of fruits per plant, average fruit weight, node number to first female flower appearance, total soluble solids, β-carotene, node number to first male flower appearance, vine length, polar circumference of fruit and negative significant association with equatorial circumference of fruit, number of primary branches per plant, dry matter content and ascorbic acid content at phenotypic level during both seasons (Y₁, Y₂) and over seasons (pooled). Analysis for the fruit yield per plant with respect to path of coefficient were found positively significant i.e. affected by number of fruit per plant and followed by average fruit weight, non-reducing sugars, node number to first male flower appearance and β-carotene at phenotypic level. The present investigation concluded that the number of fruit per plant and followed by average fruit weight, non-reducing sugars, node number to first male flower appearance most important traits for improvement for fruit yield in pumpkin.
