Correction

The authors noted that three values in Table 1 need corrections [1]. The MRF for self-pollinated diploids should be corrected from 15.4% to 16.8%, for self-pollinated autotetraploids from 20.5% to 23.2%, and for self-pollinated allotetraploids from 24.1% to 28.0%, applying the correct formula for genotype combinations upon self-pollination given in reference nine. Similar corrections need to be done to Additional Files 1, 2 and 3. See also Rehmsmeier 2012 [2]. The changes do not affect any of the conclusions presented in the original manuscript. We apologize for any inconvenience caused by this error.

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
