Major genes govern the fertilization of teosinte ovules by maize pollen. A pollen-pistil compatibility system different from the previously described systems, Ga1-s and Tcb1-s, was identified among maize lines introgressed with chromosome segments from 2 teosinte populations. The pistil barrier is dominant, and pollen competence is determined by genotype of the individual pollen grain. A major gene governing this...
