Investigation of the effect of the genotype-environment interaction on variability and stability of quantitative traits in seedless vine cultivars
A set of methods has been applied to a group of seedless vine cultivars, through which an objective evaluation has been provided of the effect of genes interacting with the environment and their influence on the variability and stability of commercially significant quantitative traits. It has been found that the effects of the genotype-environment interactions are well manifested in all traits and they should be included in the overall assessment of the agrobiological potential of cultivars and their specific utilization depending on the concrete selection or production purpose. Seedless cultivars have been arranged in an ascending sequence according to the stabilizing influence of the genotype-environment effects on the studied traits.
