Summary

Introduction

Walnut (Juglans regia L.), known as Carpathian, Persian, or English walnut is a crop grown in over 60 countries in both hemispheres of the globe. The cultivars recommended for organic farming in temperate continental climate countries are rustic genotypes, resistant to low winter temperatures, tolerant to main diseases and adapted to a climate quite rich in rainfall. Most of these cultivars come from selection activities carried out in local walnut populations. The ecological principles (climate, orchard location, soil, and biocenosis), genetic and geographical origin of cultivars and rootstocks, and technological conditions are responsible for increasing productivity, fruit quality, and economic efficiency of the crop (Burke et al, 1976; Grimo, 1979; Botu, 1998; Botu et al, 2001; Aleta et al, 2014; Botu and Achim, 2014). Research conducted at SCDP Valcea over the last 30 years has highlighted the value of walnut cultivars and the possibility of growing some of them organically (Botu et al, 2001; Botu and Tudor, 2005, Botu et al, 2010; Achim et al, 2018)
