  • a Data shown are mean ±se. Student's t test was calculated between wild-type and mutant siblings (P < 0.001 in all cases).

  • b Stp values were derived from wild-type siblings from populations segregating for either stp-3 or stp-4: wild type, 41 individuals; stp-3 or stp-4, 11 individuals.

  • c t, Student's t value.

  • d Only five stp-4 plants produced leaves bearing three or more leaflets; this value is from these five plants.

  • e Number of flowers present on the first secondary inflorescence scored from wild-type and stp-4 segregants from two separate populations: wild type, 55 individuals; stp-4, 29 individuals.

  • f ND, not determined.
