Environmental stability of triticale varieties by productivity in agricultural zone of Krasnoyarsk region

The research objective was the identification of potential opportunities of summer and winter triticale varieties, passing test on variety sites of Krasnoyarsk Region, their ecological stability. Three-year data (2016-2018) productivity of 4 varieties summer triticale (Carmen, Zaozerye, Rossika, Dobroe) on 2 variety sites (Nazarovsky, Minusinsk) and 7 varieties of winter triticale (Tsekad 90, Bard, Kapriz, Sirs 57, Tornado, TI 17, Topaz) passing test on 4 testing plots (Kazachinsky, Krasnoturansky, Nazarovsky, Sukhobuzimsky) were analyzed. The interaction of "the genotype × environment", the reliability of influence of separate factors on productivity determined the interaction by method of three-factorial dispersive analysis. Ecological stability of studied varieties was estimated by N.A. Sobolev's technique. The laying of experiments, accounts and observations on testing plots was made according to the technique of state variety crops testing. It was revealed that the contribution of studied factors to variability of productivity of winter and summer triticale had been various...
