The evaluation of ecological stability of spring soft wheat varieties on variety plots of Krasnoyarsk region

The research objective was to define ecological stability of the varieties of spring soft wheat passing test on state variety plot of Krasnoyarsk Region. For studying 16 varieties of soft spring wheat of different groups of ripeness were chosen: early ripe (Novosibirskaya 15); mid-early (Altaiskaya 70,Novosibirskaya 29, Novosibirskaya 31, Pamyati Vavenkova, Omskaya 32, Kanskaya, Novosi- birskaya 41); mid-season (Novosibirskaya 18, Sibe- rian Alliance, Altaiskaya 75, Omskaya krasa, Predgornaya, Kuraginskaya 2, Krasnoya-rskaya 12); mid-late (Svirel), passing test on 8 variety plots of the region (Krasnoturansky, Karatuzsky, Minusinsk, Nazarovsky, Sukhobuzimsky, Sayan- sky, Uzhursky, Uyarsky) on two predecessors (black fallow, grain) in 2016-2018 variety plots were covered by the main crop zones of cultivation of a spring wheat in the region (III-VIII). As a result of their studying applying the method of N.A. Sobolev (1980) according to ecological stability varieties which provided steadier productivity in sharply differing agroecological conditions were allocated: Kuraginskaya 2 (Krasnoyarsk RDIA), Krasnoyarskaya 12 (Krasnoyarsk RDIA), Novosi- birskaya 18 (Siberian RDIPGS RAAS)...
