^aThe phenotypic correlation coefficient (r_P) and genotypic correlation coefficient (r_G) were in the upper and lower line in the upper right corner of the table, respectively. The organ correlation coefficient (r_O) was in the lower left corner of the table.

^b* and ** indicate significance at 0.05 and 0.01 probability levels, respectively.
