SECONDARY POPULATIONS OF TURKISH HAZELNUT (CORYLUS COLURNA L.) IN NOVI SAD

Results of nuts morphological analysis for selected genotypes of Turkish hazel (Corylus colurna L.) refer to secondary origin trees. Seed germination and graft acceptance on seedlings was established for examined genotypes. Dependence correlation of seed germination from examined morphological features was determined. These findings could have significant importance on process of selecting mother plants for production of seedlings and planting material. Selected genotypes from nursery Gradsko zelenilo (A4, A5, A8, A13, A14, A16, B7, C1, C2, C3, C4) had high seed germination and formed thick line composition during examination year. Grafting of genotypes was done at beginning of April year 2011 intent to get high grafted hazel trees. During vegetative period percentage of graft acceptance ranged from 70.00% (genotype C1) to 93.3% (genotype A4) which implies high compatibility of rootstocks with Tonda Gentile Romana cultivar
