Özet

In this study, 10 inbreeding squash lines (C. pepo L.) which have light and dark fruit skin colored were used in order to clarify the inheritance of fruit skin colour. Summer squash lines (I6 level) were classified from light green to dark green for the criteria of fruit skin colour at mature stage of development. Inbred lines with light green fruits were crossed reciprocally with the dark green fruited lines in order to determine whether fruit skin colour inheritance had parental effect. In each cross combination, the F-1 plants were selfed to obtain F-2 and also backcrossed to each parent to produce BC1. All F-2 and BC1 generations were grown in the field and subjected to open pollination. Fruits at mature stage were harvested and their colours were scored in each individual plant. The Chi-square test was used to analyze the data. In this research, it was possible to say that genotype of the line 27 was l-1/l-1 l-2/l-2, line 39 was L-1/L-1 L-2/L-2.
