cross-pollination, shorter styles and narrower corolla apertures may promote autogamy among self-compatible blueberry genotypes ( Ritzinger and Lyrene, 1999 ). For commercial blueberry production, autogamy and self-compatibility may act as an insurance

term to describe the phenomenon of in-bud fertilization, which has also been described as “bud-autogamy” ( Noormets and Olson, 2006 ) or “preanthesis cleistogamy,” in which “self-pollination occurs in the bud, followed by anthesis and opportunities for

due to the unknown ratio of selfed fruit in the open pollination treatment, because these selections show a high level of autogamy ( Kodad, 2006 ). The pollen donor effect could explain these results; note that Vezvaei and Jackson (1995) reported
