Abstract

Hazelnut (Corylus avellana L.) is the one of the native and valuable shrub in Iran. Identification of the superior genotypes of hazelnut is the firs step for cultivation developing and breeding programs of this nut crop. In this research, had been studied phenological, morphological and pomological characters according to hazelnut’s descriptor for two years (2009-2010) on four populations of hazelnut in the category of Mamoli Gerd, nakhonak, Kolaparak and khormaie in four regions of mountain in Talesh. The quantity and quality data from phenological, morphological and pomological characters collecting by method of random sampling and quantity analyzing by the method of ANOVA and Duncan test and quality data by the method of Chi Square (X 2 ) test. The results of this study showed that studied genotypes have wide range of phonological and morphological characteristics and these were categorized in separate groups. With analysis of data, superior genotypes were identified for high productivity, resistant on spring later cold, high weight of fruit, high percent of fruit brain, and appropriate time for harvesting and resistant on pets and diseases. Development and cultivate of superior genotypes in study area can be useful to local people due increasing income and economic stimulation companion with agriculture and animal husbandry activities.
