- Abstract
For the aims of the study were used three years data for the yield, plant height, test weight and mass of 1000 grains of triticale varieties with different genotypes (Kolorit, Musala and Trismart), cultivated on the experimental field of the Crop Science Department at the Agricultural University of Plovdiv, Bulgaria. In order to determine the ecological plasticity and stability of the tested parameters, the modified model of Eberhart and Russel was applied. The yield plasticity varies from 0.825 by Trismart variety to 1.189 by Musala variety. The Musala variety is distinguished with the highest values of the plasticity bk and this variety significant is the most plastic. By the component yield with the lowest stability is the variety with the highest plasticity- Musala. The variety Trismart, who is distinguished with the highest stability, possesses also the lowest plasticity. According the component plant height all varieties manifest high stability and only the variety Musala can be accepted as ecological plastic regarding this parameter, because it possesses plasticity values of bk>1. The yield plasticity coefficient correlates positive with the plant height and the mass of 1000 grains. According the yield stability coefficient by all examined components are determined negative proven correlations.
