a
χ2 values test the fit of counts of fertile/sterile progeny of T0 or T1 plants to a 3:1 ratio.
b
The seeds from Ugp1-OX T0 plants of lines 10, 14, and 27 were soaked, sown, and transplanted on April 28, May 5, and May 27, 2004, respectively.
c
These plants were soaked, sown, and transplanted on April 22, April 28, and May 14, 2005, respectively.
