Summary. In 2014-2015 we carried out an ecological test of eight varieties of spring triticale (Ukro, Karmen, Grebeshok, Rovnya, Kunak, Yarilo, Lotas and Uzor) in three climatic zones of Amur region: south (Tambov State Variety-Testing Plot), Central (Svobodny State Variety-Testing Plot), north (Mazanovsky State Variety-Testing Plot). The aim of the investigation was to reveal the varieties adapted to the different agrarian zones of Amur region. The maximal on average in the two-year investigation productivity of the tested varieties was obtained in the south zone, it was 4.51 t/ha. In the central and north agrozones the value of this sign did not exceed 2.45 and 2.68 t/ha, correspondingly. In the south zone the maximal average productivity in the experiment was registered in Lotas (5.09 t/ha) and Uzor (4.95 t/ha) varieties; in the central one – in Rovnya (2.68 t/ha) and Uzor (2.63 t/ha) varieties; in the north zone – in Uzor (2.90 t/ha) and Karmen (2.80 t/ha) varieties. Irrespective of the conditions of the soil-climatic zones of the region the yield of the varieties of spring triticale was characterized by great variability, especially in the central zone, where the coefficient of variation was within the limits from 2.9 % (Karmen and Grebeshok varieties) to 23.1 % (Yarilo variety). The lowest value of this index (1.2–2.9 %) in all studied soil-climatic zones of the region was noted in Karmen variety. Among the eight varieties being tested the four of them (Karmen, Kunak, Rovnya, Yarilo) were characterized as plastic (the coefficient of linear regression is less than 1); two varieties (Lotas and Uzor) can be considered as intensive and responsive to the environment changing (b is more than 1). The lowest value of Si2 was found in Kunak (1.73), Ukro (2.42) and Grebeshok (2.44) varieties; the highest one – in Uzor (6.56) and Lotas (7.12) varieties. Therefore Kunak and Ukro varieties are the most adapted to the variation of growing conditions.
Keywords: triticale, crop yield, ecological testing, plasticity, stability.
