The test crosses of inbred lines developed from different cycles of BSSS (Iowa Stiff Stalk Synthetic) were used as the material to estimate the joint effects of yield components on grain yield. Seven cycles of recurrent selection led to the changes in the correlation traits. Coefficients of multiple determination of yield components on grain yield generally had higher values for the crosses where one of the parents was B84 (BSSSC7) than for the corresponding crosses where one of the parents was B37 (BSSSo). The kernel row number, number of kernels per row, and 1000 kernel weight had the highest joint effect on grain yield for both B84 and B37 crosses.
