Cross-incompatibility of two related rabbiteye blueberry cultivars

Fruit set percentage on «Aliceblue» and «Beckyblue» averaged 65% when «Climax» was the pollen parent and u 1% when the cultivars were self-pollinated. Reciprocal crosses of «Beckyblue» and «Aliceblue» averaged 24% set, indicating a high degree of cross-incompatibility. There was no effect of pollen parent on berry fresh weight, although seed weight and seed number were reduced by self-pollination or pollination by the related cultivar
