COMPARATIVE ASSESSMENT OF THE POTENTIAL PRODUCTIVITY OF THE WINTER SOFT WHEAT VARIETIES, RECOMMENDED FOR CULTIVATION IN DIFFERENT YEARS, ON THE PARAMETERS OF PLASTICITY AND YIELD STABILITY

abstract 1391805020 issue 139 pp. 65 – 82 31.05.2018 ru 2
The article discusses the results of the research on winter soft wheat which is connected with the studies of yield variability, depending on the year conditions and the variety, conducted in 2003-2014. The objects of the research were 34 varieties included in different years into the State register of breeding achievements and recommended for cultivation. The experiment was carried out by the predecessor of soybean on the medium background of soil fertility. The varieties were being cultivated both with the protection against fungal diseases and without it. The method of dispersive and variance analysis was used in mathematical processing of the yield data. The parameters of ecological plasticity (bi) and yield stability (S2) have been calculated according to the methodology of E.A. Eberhardt and U. A. Russell (1984). The range of variability has been defined according to V.A. Zykin (2000), the fulfillment of the yield potential has been set according to E. D. Nettevitch (2001). The research revealed that the new winter soft wheat varieties included into the State register of breeding achievements are mostly productive and adaptive. Their yield increases mainly due to the upper threshold. The new varieties differ in yield stability but we have not found out a certain pattern. In conclusion it must be mentioned that the implementation of Eberhardt and Russell model in analyzing yield data allows us to estimate general tendencies in its variation when the conditions of the environment change and to identify the most valuable genotypes. In order to rank genotypes according to the characteristics which are being studied we have to choose an agricultural background on which their maximum potential is realized
