Differences in fruit characters between caprifig. and other fig. types, and first and second crops among fig. (Ficus carica L.) hybrid seedlings, fruit weight (FW), and soluble solids content (SSC) in the juice of the hybrids from 9 cross combinations were investigated. The family means of the groups namely, caprifig-type first crop, fig-type first crop, and fig-type second crop were searched for and the three family means compared within the family in each group. Correlation coefficients between the groups of the three family means and the mid-parental values in 9 families were calculated. (1) For size, the caprifig-type first crop weighted the least in 8 families; the fig-type first crop was heaviest in7 families. The family means of FW in 5 families became progressively larger in the order of: caprifig-type first crop, fig-type second crop, and fig-type first crop. (2) The family means of SSC in all families became larger in the order of: caprifig-type first crop, fig-type first crop, and fig-type second crop. (3) There are positive correlations between the FW of the three groups and mid-parent and between the SSC of fig-type fist and second crop, and mid-parent. (4) There are negative correlations between the FW of caprifig-type and fig-type first crop and the SSC of mid-parent and between the SSC of fig-type second crop and the FW of the mid-parent
