^*C-high means cottony texture- high density-abundant growth; C-reg means cottony texture-regular density-regular growth and F-low means floccose texture-low density-scarce growth.

^**Growth rate (Value ± SD). Different letters indicated significant difference among growth rate values of the hybrids at level p < 0.01, according to Duncan test.

^***R is the correlation coefficient for the linear model.
