Recessive tall-a fourth genetic element to facilitate hybrid cereal production

摘要

A recessive gene for tallness in plants is used as the fourth genetic element along with cytoplasmic-genetic male sterility, sterility maintainers and fertility restorers to facilitate hybrid seed production. The recessive tall gene is incorporated into the pollen fertility restoring parent (R-line) in hybrid seed production crosses (A-linexR-line crosses).
