Plasticity and stability of some sugar beet varieties to root rot

Abstract

Variation in genotype performance depends on both genetic structure and the influence of environmental factors. Genotype x environment interaction generates discrepancies from one crop to another. Different methods have been used to distinguish genotypes according to their behavior in different environmental conditions. The study of sugar beet varieties based on 44 experiments on the following indices: root yield, quality, degree of rot is presented. The evaluation of stability and plasticity parameters highlights the most valuable hybrids according to the respective indexes.
