Stefan Gandev, Veselin Arnaudov

Abstract: Tiszacsecsi 83 is a perspective Hungarian walnut cultivar. It was introduced in Bulgaria in 2003 and grown to date in the walnut orchard collection of Fruit Growing Institute – Plovdiv. The aim of this study was to investigate the agrobiological characteristics of Tiszacsecsi 83 cultivar and to analyze the possibilities of its growing in Bulgaria. The biological characteristics and economic properties of the fruits obtained from the introduced Hungarian cultivar Tiszacsecsi 83 were compared with those of the standard Bulgarian cultivars Izvor 10 and Sheynovo. The results of the study show that the walnut cultivar Tiszacsecsi 83 is characterized by late flowering, moderate growth, low yield, low susceptibility to anthracnose (G. leptostyla) and moderate susceptibility to bacterial blight (X. arboricola pv. juglandis). The mean nut weight is 10.6 g, and the kernel output – 39.6%. In the climatic conditions of Bulgaria fruits ripen in the first ten days of October. Poor yields and low kernel output of Tisachechi 83 define as unsuitable for new industrial walnut orchards. Due to the moderate growth, late flowering and low sensibility of anthracnose, this cultivar may be of interest only for breeding purposes.
