Our collection of dwarf lines, obtained in the result of cyclical diallel crossings of genotrophs, induced by pyridine carbonic acids, zoned common wheat cultivars and short stem common wheat samples from the World Wide Collection of the Russian Institute of Plant Industry, was applied for creation of new common wheat lines having valuable morphological traits. It was observed that open blooming dwarfs were good for cross-pollination, and without insulation they demonstrated a great issue of natural hybrids. It was marked that cross-pollination promoted appearance of great number of hybrid plants with high productive tillering capacity. After individual selection among those hybrid plants and their propagation we got fertile constant lines of common winter wheat having 17-20 productive stems per one plant and a productive ear. These lines are firm and resistant to lodging. At the present time these constant lines are cultivated in conditions of resource-saving ridge technology.展开更多
