Studying the barley varieties of VIR world collection in the conditions of the Middle Urals
The aim of the study is to identify new sources of efficient selection traits and expanding the gene pool of the original raw material to create new barley varieties in the conditions of the Middle Urals. The studies were conducted in 2005-2014 with the stationary experiment Krasnoufimsk selection center. The predecessor is fallow. The area of ​​the plot is 3 m2. The repetition is double. Over the years, the studies have shown a strong variability of the climate conditions of the vegetation period from germination to maturity (the average air temperature - 13,5...18,00C, the sum of temperatures over 100C - 1200...18000C, the precipitation - 90...350 mm, the moisture deposits in the first meter of soil - 65...200 mm, the hydrothermic factor - 0.70...2.45). On the basis of studying of VIR world collection the following characteristics of agronomic traits of barley are singled out: the yield potential, the overall adaptive capacity, the yield stability, the selection value of genotypes, the maturity, the weight of 1000 grains, the resistance to local smut populations, the resistance to dark-brown spotting. By selecting the following new genetic sources of agronomic traits of barley are obtained (the productivity, the resistance to the lack of moisture in the tillering phase, namely the booting, the immune resistance to local smut populations, the earliness). Singled out and obtained by selecting the new genetic sources of agronomic traits of barley are recommended to be involved in the selection process to create a barley selection material in the conditions of the Middle Urals
