Organ dimensions and flowering time correspond to plants (12 per genotype) grown in a statistical assay during spring and flowering during summer. Variance ratio F tests: CMS I and II values are not different at the 1% level and are pooled here; differences between T and CMS are highly significant. Leaf length: length of the largest leaf measured on 2-month-old plants at the rosette stage; SP, self-pollination.
