VARIETIES BRED AT SIBNIIRS AS PARENT MATERIAL FOR BREEDING OF SPRING WHEAT IN TYUMEN REGION
Spring wheat varieties, bred at the Siberian Research Institute of Plant Growing and Selection (SibNIIRS), Russian Academy of Agricultural Sciences, were studied under conditions of Tyumen Region. There was established their advantage over the standard cultivars because of many economic and biological traits: duration of inter-phase periods, length and density of straw of the lower internodes, resistance to diseases (root rots, loose smut, Septoria disease of the ear, mildew, brown and stem rusts), yield structure and productivity. It has been found that the cultivars Pamyati Vavenkova, Novosibirskaya 15, Novosibirskaya 29 and Novosibirskaya 89 are characterized by a complex of positive traits and are valuable parent material for breeding. The cultivars mentioned persistently form high productivity and grain quality across years.
