Abstract

The aim of this work is to fix the price of the adaptive properties of spring triticale, created in different ecology-geographical zones, in agroecological conditions of the Middle Priamurye concerning the productivity. The researches have been done in 2015-2017 years on the selection crop rotation of the Far-Eastern NIISH. The eight sort samples of spring triticale from VIR world collection, created in different ecology-geographical zones, were picked out and analyzed. The hydrothermic conditions during the researching years were of various character: index of surroundings conditions changed from -5,05 to 4,95. The best conditions for the sorts were in 2017 year, when the index of surroundings had the greatest importance. The negative index of surroundings was typical for 2016 year, when the soil remoistening during the whole vegetation period became the factor affecting on the spring triticale productivity. The genotypes of spring triticale showed the different adaptive properties in hydrothermic conditions of the Middle Priamurye. The sorts of spring triticale Skory, Ulyana, Victoria showed the high stability to stress factors of growing. The maximum correspondence with the factors of the Middle Priamurye surroundings is with the genotype of sort Rovnya. The sorts of high intensive type – Skory and Ulyana – are responsive to conditions improvement. That is why they are characterized by stable productivity. Sort Victoria is concerned to ecologically plastic in the soil-climatic conditions of the Middle Priamurye. The sorts: Ukro, Rovnya, Lana, Oberig kharkovskiy and AC Certa are concerned to neutral type; according to the ecological plasticity of they have no stability in productivity forming.
