Abstract. The effect of the environment on a group of new Bulgarian varieties was investigated in three different locations for a period of 5 years. AMMI models were applied. The dispersion analysis carried out proved the different genetic potentials of the investigated varieties with regard to their ecological plasticity and stability. Varieties Kristi, Antonovka, Enola and Venka demonstrated highest plasticity and stability of their productivity.
