  • The male and female partner in each cross was as indicated. A homozygous S8 plant and a homozygous S6 plant were used as controls to verify pistil and pollen fertility, respectively.

  • a Mean pollen tube scores were determined by aniline blue staining of pistils 24 hr after pollination. Three pistils were scored for each cross. Scores were attributed as follows: 0, 0 tubes; 1, 1 or 2 tubes; 2, 3–5 tubes; 3, 6–9 tubes; 4, 10–14 tubes; 5, 15–25 tubes; 6, 26–50 tubes; 7, 51–100 tubes; 8, >100 tubes. A mean score was determined from three pistils tested for each cross.
