Adaptability of barley varieties in terms of fat content in grain under conditions of Krasnoyarsk forest-steppe

The aim of the study was to analyze possible relationship between fat content in grain barley varieties and level their stability for this biochemical trait. work involved 15 hulled barley, which were grown three years conditions Krasnoyarsk foreststeppe (Minino farm, Emelyanovsky district, Territory). Climatic research differed significantly terms temperature precipitation during growing season. After harvesting plants, measured by chemical method according GOST 13496.15-97. For varieties, two parameters ecological plasticity (coefficient variation; stress resistance index) four (indicator variety; homeostatic parameter; factor; index selection value variety) calculated indicated It found that Simon Pallidum 4727 had lowest highest (and, accordingly, minimum sum ranks) forest-steppe. G 18619, 19589 Dygyn least valuable adaptability with maximum ranks. shown a higher characterized increased values all trait, positive statistically proven Cs parameter. result obtained shows through successful oil will not decrease.
