Abstract
The studies are to select pollinated cultivars of hybrid hazelnut (Corylus heterophylla Fisch. A C. avellana L.) by testing the pollen viability and pollen-stigma compatibility. The pollen viability of 5 hybrid hazelnuts was tested with the agar culture method. The pollen-stigma compatibility among 10 hybrid hazelnuts was observed by fluorescence microscope. The result showed that the pollen viability sequence from the highest to the lowest was â1-21â, â82-11â, âLiaozhen 3â, âYuzhuiâ and âDaweiâ. The pollen-stigma compatibility testing result was that only â1-21â showed best pollen-stigma compatibility among the 5 tested hybrid hazelnuts. It was demonstrated that 1-21 was the best pollinated cultivar.
