Priority directions and some results of spring barley breeding in Volga-Vyatka region

Actual directions and main results of spring barley breeding in Federal Agricultural Scientific Center of North-East named after N.V. Rudnitsky are presented in the article. Analysis of perennial data on supply of the region with agro-climatic resources have shown that there is a tendency to increase in temperature regime and decrease in amount of precipitations during whole season of growth and development of barley plants. Under conditions of central agro-climatic zone of Kirov region, plants suffer a lack of moisture during growth stages “tillering” and “heading”. Authors suggest paying much attention on mismatch in time of beginning and duration of main stages of ontogenesis with favorable growing conditions at search of initial material for breeding under conditions of increasing unstable amount of precipitation and temperature regime during growth and development of plants. Part of influence of climatic conditions and effect of genotype x environment interaction within breeding barley lines was established. Lines having high ecological stability were selected with methods based on estimation of yield capacity in years differed by weather conditions for further breeding activity. Growing up of previously bred varieties Novichok, Tandem, Pamyati Rodinoy and other justified that used methods of creation of spring barley varieties are rather effective.
