Plants from the td1-glf; kn1-E1 F2 family were grown in the greenhouse and observed. (A) Unpollinated ear spikelet counts. Numbers are mean values with standard deviations in parentheses followed by the number of plants measured. (B) P-values of a two-tailed Student's t-test of ear spikelet counts comparing the genetic classes. **Values are significant at the 1% level; ***values are significant at the 0.1% level.
a
Numbers of spikelets were counted from a cross section of the ear at its widest point, ∼1 cm from the ear tip.
