  1. Mean (SD) numbers of seeds, aborted seeds, unfertilised ovules and percent germination for various crosses to explore the possible causes of aberrant segregation ratios. F-values for one way ANOVAs are provided. Means with the same superscript do not differ based upon Scheffe's test.
  2. *Percent germination data are based upon four pots per cross each containing 50 seeds.
