A study of local and introduced walnut cultivars was carried out at the Fruit-Growing Institute – Plovdiv in the period 2018 – 2020. Four introduced walnut cultivars – two Romanian (‘Valmit’ and ‘Valeris’) and two Turkish (‘Şebin’ and ‘Yalova 1’) – and the standard Bulgarian cultivars ‘Izvor 10’ and ‘Silistrenski’ were the object of the study. Their vegetative habits were investigated and biometric measurements of the nuts were performed. Based on the results obtained the pomological characteristics of the studied cultivars were evaluated. When grown in the conditions of South Bulgaria, the cultivars introduced from Romania – ‘Valmit’ and ‘Valeris’ and from Turkey – ‘Yalova 1’, are characterized by very large nuts. ‘Izvor 10’ and ‘Şebin’ have a high kernel ratio.
