Preliminary results of tests of grapevine rootstocks resistance to lime-induced chlorosis

Abstract

Resistance to lime-induced chlorosis is very important characteristic of grapevine rootstocks. Lime-induced chlorosis influence yield and quality of grapes. Evaluation of chlorosis resistance is very important for grape growing and breeding. The aim of this work is provide results of evaluation grapevine rootstocks to chlorosis. High resistance was show in Fercal. From the viewpoint of the resistance to chlorosis, the rootstocks registered in the State Variety Book of the Czech Republic can be ranked from the most resistant to the most sensitive as follows: Craciunel 2 - SO 4 - Kober 125 AA - Kober 5 BB - Teleki 5 C- Amos - LE-K-I.
