Table I. Segregation of self progeny and the genetic transmission of a36/+ and a39/+.
Reciprocal crosses were performed between a36-2, a36-3, and a39 heterozygous plants and wild-type plants. The transmission efficiency (TE) of gametes was calculated as follows: TE = number of progeny with the a36-2, a36-3, and a39 allele/number of wild-type progeny × 100%. The observed TE was compared with the expected TE for normal gametes (100%). TEF, Female transmission efficiency; TEM, male transmission efficiency. χ2 indicates the χ2 test (degrees of freedom = 1, P < 0.05, χ2 > 3.84). NA, Not applicable.
