Introduction of new plastic varieties as an innovative factor of savings in a climate change context

The article gives an assessment of genotypes of spring soft wheat varieties created by scientists breeders of the Ulyanovsk Research Institute and in community with other selection institutions by parameters of productivity and ecological plasticity. The studies were carried out in soil-climatic conditions of the Ulyanovsk region in 2014-2018. The characteristic of varieties of spring soft wheat according to valuable economic characteristics and bakery properties is presented. According to the stability of productivity and plasticity indicators, varieties: Ekada 109, Ekada 214, Burlak and Ulyanovskaya 105 have the least dependence on weather and climatic conditions of the growing period. The maximum realized grain yield averaged 8.55 t/ha during the test years, that indicates a high productivity potential for the created varieties. The calculation of the annual economic effect of the variety changing the base class Simbirtzit to the prospective class Ulyanovskaya 105 allows to obtain an additional net income of 16270 rubles per 1 hа, or more than 1.6 million rubles from 100 hа of sowing area.
