Winter hardiness is a major factor limiting winter rye productivity in the north-east of the European part of Russia. The problem of a rye's winter hardiness under conditions of climate change is solved by breeding in parallel with creation of resistant agro-phytocenoses. Terms of the termination of autumn vegetation have changed in connection with warming; the period of development of plants before leaving at winter has increased. It leads to over-growing of plants, its damage by wreckers and the strengthened of defeat by snow mould. The article presents results of researches on studying of sowing data and seeding rates of a winter rye variety Falenskaya 4 for obtaining of stably high grain productivity under conditions of the Kirov region. Experiences are spent in the North-East Agricultural Research Institute (the central part of the Kirov region) in 2008-2010 and at Falenki breeding station (east agro-climatic area of the central zone of the Kirov region, 2011-2013). Results of studying have shown that in uncontrollable conditions of a changing climate it is recommended to displace sowing data of a winter rye variety Falenskaya 4 for 5-10 days from earlier established calendar term. In the central part of the Kirov region optimum sowing data is the period from August, 25 till August, 30th, in east agro-climatic area of the central zone of area - on August, 20-25th. For creation of optimum density of agro-phytocenosis the seeding rate of 6 million germinated seeds per 1 hectare is recommended which has allowed to generate a maximal grain yield on the average for years of studying.
