biological and pomological properties of some walnut selections from the native population

Abstract

The paper presents major biological and pomological properties of walnut selections singled out from the region of Central and Eastern Serbia over 2002-2005. The selections are abundant croppers of extremely high vigour. The vegetation cycle begins mainly in the third decade of April, whereas flowering and inflorescence formation occur in first decade of May. Fruits ripen in the third decade of September. These selections are extremely resistant or resistant to low winter temperatures and resistant to moderately resistant to Gnomonia leptostyla. The fruits are mainly medium large or large with fruit weight ranging from 14.0 - 11.3 g. The kernel is light colored or yellow of good or very good taste, with high kernel ratio (50.0 - 45.1%). The majority of these selections have high oil content (68.2 - 61.8%) and medium raw protein content (18.3 - 15.4%). All the stated selections should be taken into consideration in respect of collection establishment and deserve to be excessively introduced into production upon testing under the respective conditions. .
