Germplasm Phenotype:

• frh1 hpat1 hpat3  — Fertility increased relative to hpt1/hpt3 double mutant alone.Suppression of hpt1/hpt3 phenotype. Increased silique length and seed set due to increased pollen germination and pollen tube growth.
• hpat 123  — Short siliques, reduced fertility. Defects in transmission through pollen due to defects in pollen tube growth.
• sec15a hpat1 hpat3  — Fertility increased relative to hpt1/hpt3 double mutant alone.Suppression of hpt1/hpt3 phenotype. Increased silique length and seed set due to increased pollen germination and pollen tube growth.
