1 Detailed values for individual plants are given in Additional Files 1,2 and 3

2 Transmission of the meiotic recombination tester through maternal (female), paternal (male) or both gametes (selfed) determined by reciprocal crosses (female, male) or self-pollination.

3 Seeds showing both red and green fluorescence.

4 S.D. - standard deviation, calculated from the individual crosses/self-pollinations in Additional Files 1, 2 and 3
