Inheritance of immature fruit shape and production in summer squash (Cucurbita moschata)

Two inbred lines of C. moschata were crossed to obtain Fl, F2 and F1BC1 for both parental generations to study the inheritance of immature fruit shape and production. Four replications for each generation were choosen in a randomized block design. For each one of the eleven harvestings, the following parameters were evaluated: weight, length and diameter near peduncle and style ends of the immature fruits. Through the results it is concluded that there is dominance for higher growth speed of the fruits, which determines greater length, diameters and weight, when they were harvested at the same age, and, therefore, greater yield per plant.
